I ahve been dealing with a problem where whenever I try and open up balatro i get this error window pop up. I am on arch linux running proton 9.0-4. I do not get this error for any other game and all my graphics drivers are updated properly.
#opengl 2.1 required

Only lead is that it stopped for someone after unplugging their controllers https://github.com/Steamodded/smods/issues/536#issuecomment-2867677193
had the same problem, just check if you have controllers plugged in, and disable steam xbox or dualsense support
