After a recent patch, Space Marine 2 gamers reported the error code AVF on Windows 11, Linux and Steam Deck. The developers know about this problem and promised a fix. However, days have passed since users can’t log into their online servers. If you were playing on Linux, the developer retired the linux64 anticheat module so you can’t do much about it. If you’re playing on Windows 11, we have the solution below.

How do I fix Space Marine 2 Error Code AVF?

1. Delete the game’s configuration file and verify game files in Steam

This will reset any modes or cheats you might have installed and get a fresh configuration file.

2. Allow the game through the firewall

Basically, this solution will provide access to the game executable files and the EasyAntiCheat through the firewall. If you have a third-party firewall, disable it prior to applying this solution.

If you’re playing the game through the Epic launcher, there are a lot more files to allow through the firewall with inbound and outbound rules: EpicOnlineServiceUserHelper, EpicOnlineServices, EpicOnlineServices.exe, EOSOverlayRendered-Win64-Shipping.exe, EasyAntyCheat_EOS, eac_launcher.exe.

Since there is a longer process, we simply recommend reinstalling the game, which will have the same effect. Just remember to back up your saves first.

The error code AVF is caused by a conflict between some of the modes you’re using that are trying to bypass the EasyAntiCheat. By resetting the mods, you will be able to play the game on Windows 11 without any issues.

Hopefully, by applying the solutions above you’ve fixed the Space Marine 2 error code AVF on Windows 11.
