How to fix Valheim crashes and errors?

Issue: Hi, I have heard good things about Valheim, so I bought it on Steam. I had a lot of fun, but the games started crashing pretty often. I am not sure whether it is the game's fault or there is something wrong with my Windows PC? Anyways, it would be nice if you'd provide some solutions for Valheim crashes.

Solved Answer

Valheim is an open world survival game released on February 2, 2021, by Iron Gate – a developer from Sweden. The studio's debut indie title was met with high positivity from both gamers and journalists.[1] According to the developer, just within 13 days of the alpha release, more than 2 million players purchased the game.[2]

Despite the initial game's success, it did not avoid criticism. Many users claimed that it is riddled with game-breaking bugs, while others said that it is practically unplayable due to Valheim crashes. While the title is still in the alpha stage,[3] people are enjoying it greatly, and it is not fun when this experience is ruined by technical issues.

Therefore, many players rushed to Steam, Reddit, and other online boards to find solutions for Valheim bugs and crashes. When it comes to bugs, barely anything can be done by users themselves, as game developers need to provide solutions for those.

However, when it comes to Valheim crashing, there could be many reasons why that is happening. In particular, application errors and crashes on Windows can be caused by corrupted system files, incompatible software, outdated or damaged graphics drivers, failing hardware, and other technical issues.

Essentially, Valheim is not the only game that suffers from various technical issues. Even well-established games such as Minecraft, Roblox, or World of Warcraft to this day experience lag, crashes, and other issues, despite them being released years ago. Cyberpunk 2077 was another title that suffered from multiple crashes and bugs upon release as well.

How to fix Valheim crashes and errors?

People reported that there are several different instances of how the game crashes. In some cases, they would get a simple “Valheim.exe is not responding” pop-up, which would shut down the game. Additionally, Unity errors were also common:

Most up-to-date graphic card drivers are vital for any gaming experience. Besides, drivers might sometimes just stop working correctly due to one reason or another. Therefore, it is important to make sure that your GPU drivers are updated. You can try to update them via three different methods:

Update drivers via Device Manager

  • Right-click on Start and pick Device Manager
  • Expand the Display adapters section
  • Right-click on your graphics card and select Update driver
  • In the new window, pick Search automatically for driver software Update GPU drivers
  • Wait till Windows installs drivers and reboot the PC.

Download drivers from manufacturer's website

A much more efficient way to install drivers is by visiting your hardware manufacturer's website. It is not a secret that Device Manager straight out fails to find the latest drivers automatically, so it is far from a perfect tool. To download drivers from the official website, you will have to know your device model. Here are the links to the AMD, Nvidia, and Intel websites:

Use automatic solution

Access geo-restricted video content with a VPN

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
