I have tried to install the suggested DLL of "crypt32" but this doesn't seem to work. Before I do this the game launches but stuck in "conneting to Steam" loop. Once install with protontricks it fails to even launch. It just says "playing" then suddenly it stops and closes like it crashes or something. Steps bellow.

• Must run the game once, and install and/or run protontricks.
• Select Nightingale fromt he GUI list and hit "OK".
• Select the default wineprefix and hit "OK".
• Install a Windows DLL or component, and hit "OK".
• Find in the list "crypt32"/"MS crypt32", tick that option and hit "OK".
• You might run into errors and have to wait a bit untill a new windows comes up. It's downloading the crypt32.

Unless the the ProtonTricks works for you, the only other option is the launch options for mangohud %command% -ignore-windows-system-certs which does work but not recommend.
