[2020] Game crashed upon startup in official realm

Are any other errors displayed, other than the crash report produced?

Are you using Avast, AVG, BullGuard or SpyBot?

It’ll be AVG. Try adding the Vermintide 2 directory as an exception, and if that doesn’t work, you may need to reinstall AVG.

Hmmm I don’t know of any other workaround other than adding an exception, which I appreciate has been unsuccessful for you. I’m not sure why AVG and some others interact so badly with Vermintide 2.
