Hello.

Thank you for the report. This error is very generic. It may be caused by many issues, such as a hardware malfunction, a virus in the computer, but also an error in the game itself.

Possible solutions:

• Try joining another server, then rejoin the previous one.
• Update the graphics card drivers to a newer version.
• Rollback the graphics card drivers to an older version.
• Check the temperature of your GPUs and CPUs.
• Verify the integrity of the game cache using Steam.
• Re-install DirectX.
• Uninstall the Visual C++ 2013 Redistributable package (both x86 and x64 version), restart your computer and install the package again (do not use the Repair function).
• Run a Windows System File Check tool to repair corrupted system files.

Error occurs in everyone without exception. I develop the server and this problem only appeared after the last DLC

please try the performance binary from profiling branch , it contains multiple crashfixes
