With Proton enabled, co-op works but Steam launches Stardew Valley without SMAPI or my mods. Without Proton, SMAPI works, but co-op gets stuck on "connecting to online services".
I've tried an older Proton version, a Linux co-op fix, Wine, and reinstalling. I also saw the same issue on EndeavourOS and Fedora. What should I check next?
SMAPI has a native Linux version, so one option is to keep that setup and troubleshoot the co-op connection separately. Proton isn't required just to run SMAPI.
Check whether the unmodded native game also gets stuck connecting. That would help narrow down whether the problem is related to SMAPI or the game's online connection.
For the Proton route, check how Steam is launching the game. If it starts the regular game executable instead of SMAPI, changing Proton versions won't necessarily make your mods load.
Double-check the SMAPI installation instructions for running the Windows version through Proton and compare them with your Steam launch options. Treat any Wine error as a separate clue rather than assuming it explains why Steam bypasses SMAPI.
Could you post the exact Wine error and your current Steam launch options? Also say which Proton version you're using and whether the game opens at all when you try to launch SMAPI through it. Those details would make the next troubleshooting step much less of a guess.
