I bought the indie subscription on Steam to try out Painter for a month. However, when I launch in Steam nothing happens. It simply quits without any screen appearing and no error message. I have tried different proton versions and also without so that it tries to run native Linux version.
Initially I had a libtiff symlink issue that I resolved. Now if I try to launch it from the terminal I get the error qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in "". I have searched the web, but I cannot figure out what causes this issue and how to fix it.
