I am trying to run Crusader Kings 3 on Linux Mint. For some reason, it keeps crashing on the initial loading screen. It's a fresh install with no mods.

I have every DLC as well.

Has it worked on Mint on this computer before?
 
Note that the only supported distro is Ubuntu. But let's see if we can help anyway.



I know of two possible causes to this problem on Linux.

One is if you've used the Snap or Flatpack installs of Steam, which do not work well with our games. You need to use the native Linux client from Valve:

"Install Steam Now"

The other is an issue with Steam when you have Proton installed; Steam sometimes thinks you have the game on WIndows not Linux so installs the wrong version. If you see ck3.exe (ie the Windows executable) in your Steam folder for this game, that is the problem!

You can get past that as described here:

All the best!
