I would recommend that you uninstall Vermintide 2, delete your AppData (important!), restart your machine and subsequently reinstall. You can delete your AppData by:
- Press Windows key + R
- Enter %appdata% within the search input and select ‘OK’
- Navigate to \AppData\Roaming\Fatshark
- 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.
