I’ve been able to run all of my other regular games since switching to Pop!_OS, but one is giving me a problem still, Space Engineers.
Tried all of the Protons (and Proton-GE), tried various launch options, read all of the feedback left on protondb website for the game, looking for any other ideas. :)
Do you have the epic games version of civ 6?
That don’t work for me, but the Steam version works just fine.
