[Nocccer]

Describe the bug

The save path for witcher 3 does not show up and the circle is spinning endless without error report in frontend.

Add logs

Steps to reproduce

Select proton 7.0 and try to load sync-save settings.

Expected behavior

It fetches the path correctly or showing an error in the frontend atleast and let the user select the path afterwards, manually.

Why wine in Proton isn't found is another story.

[Nocccer]

I would asume the runinprefix is not compatible with proton.

[Nocccer]

What about taking this instead runinprefix and calling the wine executable in proton? https://wiki.winehq.org/Regedit

[imLinguin]

runinprefix does literally that, runs bundled wine executable instead of wrapping it in steam.exe like proton would normally do

[redromnon]

It's happening to all GOG games in my library apparently, including the ones that don't support save syncing like OpenTTD (Linux). The Save-Sync option shouldn't even exist for such games, if I'm not wrong.

Can't reproduce it sadly, Game: Tomb Raider: Anniversary save location: <?DOCUMENTS?>/Eidos/Tomb Raider - Anniversary

[imLinguin]

could this be somehow caused by flatpak and it's permissions?

[redromnon]

I've created a separate issue #1721 for it instead. Doesn't fit here.

[Nocccer]

Not a flatpak porblem. Works on my pc. I need to test on steam deck then.

Ok tried back and this time it worked. Maybe it was a error with the proton 7-03 version. With proton 7-04 it works.
