1. Start a DayZ Server with at least one mod from the Steam Workshop you want to connect to (My Server has a password, which might be important to have, because the crash happens when the password prompt opens)
2. Open the DayZ Launcher (and have the Server in your favourites)
3. Got to the Mods section of the Launcher and repair a mod (usually needed when I had to get an update from a Serverpack)
4. Try to join the Server and hit ok when the Mod section opens
5. The Password prompt will popup and the Launcher Freezes and crashes

I tested it on both my Laptop and my PC and both were crashing
