I have tried:
Reinstalling the game
Reinstalling vcredist
Reinstalling directx
Reinstalling .NET files
Verifying game files integrity
Deleting Crusader kings II file from documents/paradox interactive
Running as administrator
Running compatibility troubleshooter
Deleting all the flag files
Restarting pc
Turning off shields on Avast and starting the game
None work, and there are no apparent error logs in either Documents/Paradox Interactive/Crusader Kings II or steamapps/common/Crusader Kings II
