Hmm, we’re having some difficulty reproducing this our end.
Could you please launch the game using the bypass launcher workaround, attempt to connect to a game/friend and then provide us with your console log from the session? This would let us see what’s happening under the hood and could really help 
To do so:
- Press the Windows key + R
- Enter %appdata% within the search input and select ‘OK’
- Navigate to AppData\Roaming\Fatshark\Vermintide 2\console_logs
- Locate the console log that corresponds with the session in which the issue occurred, by looking at the timestamps in the log names
- Upload* the appropriate console log to us
Thanks in advance!
