[2021] Same problem with .dll file after new patch

Unfortunately it sounds like you’ve exhausted all of what we would usually recommend, so in all honesty I’m not sure we can come up with an immediate solution.

The next step would be to reach out to Easy Anti-Cheat directly, as this is an error produced by their service. We can either do this on your behalf, but they usually prefer to speak with the player: Easy Anti-Cheat

Alternatively, providing Vermintide 2 was purchased via Steam, I’m happy to contact them and request that they issue you a refund.
