So, in relation to a seemingly pretty widespread issue where Valheim causes crashes/freezes/BSOD, more specifically mentioning a UnityPlayer.dll Access Violation.
I spent a couple of days troubleshooting and I think I tried every possible fix mentioned on this subreddit and elsewhere, such as (but not limited to):
-
turning down graphic settings
-
turning off continuous music
-
forcing Performance mode in NVIDIA driver
-
forcing Exclusive Fullscreen
-
trying Vulkan
-
getting rid of all overlays and related programs (discord, Afterburner, Steam in my case)
-
getting rid of overclocks/ undervolts (even though mine were 100% stable in all scenarios except Valheim)
-
setting High priority on Valheim.exe process
-
setting the Valheim.exe process to only use 2 cores on processor
None of this worked. BUT I did finally come across an actual solution that did fix the issue, and I have played for over 15 hours since across 3 different sessions without a hitch.
Set your RAM speed to base speed (2133 MHz) — not XMP, my modest 3200/CL16 XMP still crashes within 5-10 minutes, sometimes also BSODing with 3-4 different error messages.
This should fix specifically the UnityPlayer.dll related crashes; however there are more types of crashes such as the one related to dx files/ GPU.
I hope this helps someone to be able to play this (a bit unpolished) gem of a game.
UnityPlayer.dll — это файл библиотеки динамической компоновки, разработанный компанией Payload Studios для такого движка воспроизведения как Unity Technologies ApS.
Файл UnityPlayer.dll предназначен для создания 3D игр или анимированных персонажей, и также для правильной работы игр созданных на движке Unity. Если данный файл отсутствует или не найден в Windows 10 или Windows 7, то выскочит ошибка следующего вида:
- Система не обнаружила unityplayer.dll
- Файл unityplayer.dll не найден
- Файл unityplayer.dll отсутствует
- Не удается найти [ПУТЬ] unityplayer.dll
- Не удается запустить [ПРИЛОЖЕНИЕ]. Отсутствует необходимый компонент: unityplayer.dll. Пожалуйста, установите [ПРИЛОЖЕНИЕ] еще раз.

Вы должны понимать, что файл UnityPlayer.dll имеется во всех движках как Unity и лаунчерах как Steam или Epic. Многие сайты заставляют вас скачивать со сторонних источников отдельно dll файл и закинуть его к себе на компьютер по неправильному даже пути (в системные папки), но где гарантия, что там не вредоносный файл? Если вам нужен отдельно файл, то не легче его взять с официальной какой-либо игры? У меня имеется данный файл в игре AmongUs игрового лаунчера Epic Game.

Исправить ошибку отсутствующего файла UnityPlayer.dll
Разберем, где можно взять файл UnityPlayer.dll и как исправить ошибку его отсутствия в Windopws 10 или 7.
1. Блокировка файла антивирусом
Отключите на время антивирусный продукт и установите заново игру или программу.

2. Ошибка в играх
Если вы используете такие игровые лаунчеры как Steam, Epic или Uplay, то вам стоит переустановить игру или сделать целостную проверку файлов через сам лаунчер.
Если у вас есть подобные игры или программы, а ошибка к примеру в другой игре, то вы можете скопировать файл.

3. Регистрация UnityPlayer.dll в системе
Для Windows 10 и Windows 7 DLL библиотеки нужно регистрировать, если файл отсутствует в программе, которая устанавливается части своих библиотек в системные папки как system32 и syswow64. По этому, запустите командную строку от имени администратора и введите следующие ниже команды.
regsvr32 /u unityplayer.dllregsvr32 /i unityplayer.dll

4. Удаление Citrix Workspace
Многие пользователи на форуме Microsoft решили проблему удалением программы Citrix Workspace.

I have a problem to run this game more than 20 minutes.
Every time I get a crash with this message:
<<Valheim — Unity 2019.4.16f1_e05b6e02d63e>>
After rejoining my world with my character it is like to load a old save game.
The completely process from the last time is away!
What I have tried to fix this Problem:
— Reinstallation of Windoof 10
— Switching the GPU (2080ti to 1070)
— Nvidia driver update
— Nvidia Control Panel settings switching
— Physix
— Vsync
— Tripple Buffering
Nothing helped me. The problem still remains.

Googled that error message for couple minutes and it could be caused by your gpu being overclocked, even with stock overclock. or caused by 3rd party applications like geforce now or msi afterburner etc.
Also someone fixed issue with this error by turning off their vpn.

All this do not fixed the problem. I have the same issue, also found the descriptions by google and more as you listed here (I listed it in an other thread on the next page). Even a clear Windwos 10 re-install did not fix it.
Did you play with executables and compatibilities?
Did you try older gpu drivers/updates motherboard/cpu etc?
Which version of windows 10 are you both running?
Think there were some updates released recently, might be linked to that.. perhaps try to uninstall couple latest w10 updates, think they auto install during initial installation as a default

I have the same issue using Win7.
Things I am currently trying (I tried most everything found on Google searches already, including nvidia control panel tweaks): I am currently trying out a -opengl switch in launcher parameters in case it is a dx11 issue, and found a 2020 realtek driver some computermaker (dell or levovo or someone) tweaked for their users (latest official realtek is 2017). Set max framerates at 30, running offline mode with fullscreen, installed k-lites codec fixes, i usually «logout» every 15 minutes or so to save progress and check for any suggestions again.
This latest run, I haven’t «yet» rebooted, but everytime i thought I had a fix it eventually resatarted my computer again 🙁 so i am not that optimistic that it is something we can fix on our end, but I am really motivated to keep trying. Everytime I find another «solution» on google search, I try that but they never work for me 🙁

And it is not working for me.

First of all, thank you for your help and advices, you are the first one who replies to this topic!
Its Windows 10 Pro and there are no executables in the background. First after the clean re-install, I installed the necassary graphic driver followed by the steam client and finally Valheim, so just the pre-installed system-drivers were installed, to test whether it works or not . Even after a new crash I did install the rest of the current drivers. VPN is disabled.
First I will choose your advice to run it in compatibility mode, thats what I have not tried untill now. If this do not work I will check the latest windows updates.

I have the same problem. The game starts only if the drivers are completely removed. Through the DDU application, but when you install the driver, the problem remains

Wish I knew hot to help. will try to think of some other stuff that often causes issues in games.
Just checked their official bug list and i couldnt see this error there- would strongly recommend to submit it there asap to get this issue exposed to devs:
Edit: Btw, if you go to C:UsersusernameAppDataLocalLowIronGateValheim
There should be a player.log — does it show any error messages there?
Alternatively, there is a path for error log:
Maybe post some of the errors here so we can see and try to narrow down root cause?

Valheim might be one of the hottest games on the market at the moment but sometimes it can be unplayable due to Unity engine crashing bug. Luckily, it seems that the fix for this one is pretty easy.
Valheim took Steam by the storm, selling more than 6 million copies since its launch in Early Access. We have to say, it’s one of those games that nailed the gameplay perfectly, which is not an easy task, especially for survival games.
Iron Gate’s title is currently in the Steam Early Access phase, which means it’s nowhere near its final release. You’ll encounter plenty of bugs, crashing and other issues and one of these is Unity engine crash, which can make the game unplayable at times.
If you are experiencing this issue, fear not, the fix is pretty easy but as always, it might not work on every single PC. Here’s how to fix Unity engine crashing in Valheim:
- Right-click on Valheim in your Steam library
- Click Properties
- Uncheck «Enable the Steam overlay while in-game»
- Uncheck «Use Desktop Game Theatre while Steam VR is active»

As we already mentioned, this fix may not work on every PC but as soon as we unchecked both of these options, the crashing actually stopped so it’s definitely something you should at least try until the devs release a patch with a fix for this particular issue.
Играю в нее 2й день и на 2й день после 2 часа игры в какой-то момент зависла картинка и выскочила эта ошибка, после повторного захода в игру она появляется почти сразу (игру переустанавливал, unity обновлял)
![]()
У меня такое появилось после какого-то обновления. Запускаю игру — во время заставки появляется окошко Unity — игра сворачивается.
Помогло только вручную удалить игру из папки стима. Я предполагаю, что это был конфликт версии мода с версией игры. Сперва удалял через библиотеку Стима, но Стим не удаляет пользовательские файлы. Т.ч. пробуй

Game that use the Unity Engine often lead to crashing problem with the error Unity. The same engine is used by Valheim and users are reporting of seeing persistent crashing that’s preventing them from progressing. The game crashes unannounced wiping any progress and completely hampers the experience of such an amazing game. If you are encountering the problem, the issue needs to be fixed before you can play without having to revisit the same stage all over again. Keep scrolling and we will show you how to fix Valheim Unity error – crashing with error Unity.
The error message appears as Valheim – Unity 2019.4.16f1_e05b6e02d63e. There can be a slight variation in the code, but the error is the same. The most common reason why the Valheim Unity error occurs is due to overclocked GPU or RAM. This includes the factory overclocking or the Intel Turbo Boost.

- Right-click on Valheim.exe and click on Properties
- Go to the Compatibility tab
- Check Disable fullscreen optimizations and Run this program as an administrator.
Revert Overclocking
Once of the main causes of the Valheim Unity error is overclocking of the CPU or GPU. If you are using third-party software like MSI Afterburner to overclock the CPU or GPU, it must be disabled. Turbo boosting features need to be disabled as well from the BIOS. Ensure that the game runs without overclocking.
Go to the computers BIOS settings and disable the ‘Intel Turbo Booster’ if you have it enabled. To prevent the game from crashing, you should reset the CPU and GPU to chipset manufacturer specifications.
Underclock RAM & GPU
You must note that even when you have not manually overclocked the GPU or RAM, it may still be factory overclocked. Hence, you must Underclock the RAM and GPU. If you are using a software to overclock the GPU, disable the software and revert the settings. To Underclock the RAM, you can do it via the BIOS. A user that resolved the problem under clocked his 8GB RAM from 2000 MHz to 1600 MHz and it fixed the Valheim crashing with Unity error. You may have to tinker a bit to find the ideal setting. This fix is for advanced users and if you don’t know what you are doing, don’t try it.
Alter the Power Options in Window 10
For users who do not have an effective CPU cooler, you may want to skip this step as it would increase the CPU temperature by a few degrees. Without proper cooling, it may harm your system. Here are the steps to follow.
- Click on the battery icon in the System Tray and drag the button to Best Performance
- Right-click on the battery icon and select Power Options
- Click on the Change plan settings link
- Click on Change advanced power settings
- Locate Processor power management and click on the plus sign to expand
- Expand Minimum processor state and set it to 100%, next expand Maximum processor state and set it to 100%
- Click on Apply and OK to save the changes.
At the moment, we only have these fixes to recommend, but if they don’t work let us know in the comments and we will try to help you. Hope your Valheim Unity Error is fixed.
