I'm in the same boat. Didn't get prompted to overwrite, and the issue still persists. Anyone know what to do?
I was here. I believe as a result from installing SMAPI using a mod manager.
I downloaded smapi manually used its linux -sh to uninstall smapi, then reinstall.
Next drop in this threads library files into root of sdv. And presto coop works.
I'm on steam deck btw, also I believe these 2 files are just the result of running that command mentioned in other threads using a package that the deck doesnt work on. A user was just kind enough to share em. Im on glibc 2.41+r47+g046b33800c3e-1 and was having issues till I performed the steps I mentioned.
Bonus tip on the deck set the game resolution to 2560x1600 using the games "manage" options in gaming mode, and tick the box for internal/external. this should fix any ui scaling and make the games pixel art look great!
