From the logs, the error code produced indicates this may be due to Anti-Virus/Firewall software.
Please ensure you have appropriate exceptions in place for both Vermintide 2 and Easy Anti-Cheat.
You’ll want to add exceptions for -
vermintide2.exe in C:\Program Files (x86)\Steam\steamapps\common\Warhammer Vermintide 2\binaries
EasyAntiCheat.exe in C:\Program Files (x86)\EasyAntiCheat
A Selective Startup can also help identify whether a background application is the cause:
- Press the Windows key
- Type ‘msconfig’ and select ‘System Configuration’
- On the ‘General’ tab, select ‘Selective Startup’
- Deselect ‘Load startup Items’
- Reboot your PC
If the issue no longer occurs after having performed the Selective Startup, try re-introducing your programs one-by-one to determine which is the culprit.
