Summary​

Game does not start under linux anymore

Description​

Clicking "Start" in steam does not start the game.

Output when starting steam from the console:
/bin/sh\0-c\0/home/chris/.local/share/Steam/ubuntu12_32/reaper SteamLaunch AppId=1158310 -- /home/chris/.local/share/Steam/ubuntu12_32/steam-launch-wrapper -- '/media/chris/secondary_storage/chris/SteamLibrary/steamapps/common/Crusader Kings III/launcher/dowser.exe' -nakama -simultaneouschunks 2\0

It looks like the windows version was installed instead of the linux one? EUIV at least has separate "dowser" executables for windows and linux

Steps to reproduce​

Install the game in steam under linux and attempt to start

Game Version​

1.11.1(Peacock), Checksum 8c7c

Platform​

Linux

Funnily enough, it works when I use proton. Looks like there is some hidden setting left over from my experiments with proton to circumvent the constant crashes under linux, that persist to a complete reinstall?

How do I return to the actual linux install?

Ok, switching now away from proton leads to a small update and the game launches again.

And after a restart of steam, the windows version is installed again, wtf?

I had this bug with Proton too. Reinstalling the game didn't help and I had to remove Steam, remove all Steam directories and install it again.
