The most common cause is a file being blocked which conflicts with the Anti-Cheat. You can check your service.log in C:/Program Files/FACEIT AC and see if there are any blocked files.
Some of your Windows files or video driver files might be modified and/or corrupted. Please try the following solutions:
- Do a system scan with Malwarebytes Anti-Malware to find any malware that might have modified critical windows files
- Check for corrupted Windows files with the System File Checker
- Search on Google the blocked file name, that will probably tell you from which program it comes from. If the file is related to your video/network/audio drivers, simply updating them to the latest version should resolve the issue.
- If you installed Smart Game Booster, please try to uninstall it, as this application modifies DirectX system files.
- Make sure that the game executable is not set to run as Administrator. Go to the game directory, right click on the executable (e.g. csgo.exe), click Properties, Compatibility, and untick "Run this program as an administrator".
If you have this problem in CS:GO, it might not be caused by the AC, but by a third party application running on your PC. The AC will always launch CS:GO with -allow_third_party_software, which means that 3rd party applications will be able to load their DLL inside the game. It is possible that one of these 3rd party applications running on your PC is causing the game to crash.
Please try to add -allow_third_party_software to your launch options, close the Anti-cheat, start the game. If the game still crashes, then the crash is not linked to the Anti-cheat.
