I would recommend that you uninstall Vermintide 2, delete your AppData (important!), restart your machine and subsequently reinstall. You can delete your AppData by:

1. Press Windows key + R
2. Enter %appdata% within the search input and select ‘OK’
3. Navigate to \AppData\Roaming\Fatshark
4. Delete the entire ‘Vermintide 2’ directory

Please be aware that this will remove any custom configurations, and may prompt you to re-run the prologue. Sorry!

Afterwards, please restart your machine and reinstall Vermintide 2.
