For civ 6 if you haven’t already try the proton version I’ve found it much more stable than native Linux.

I basically never run the native Linux versions anymore, Proton is always more stable and more performant.

I think that's actually Valve recommendations to developers as well: don't bother with the fast-moving and always breaking APIs and ABIs of native Linux support, just make sure your game works well with Proton.
