SyncThing will not sync for Azahar on Steam Deck

Hi, I have succesfully managed to sync the folder in which I store my games for emulation purposes through my desktop and my Steam Deck using SyncThing.

However, trying to sync saves, for Azahar has repeatedly failed and I’m at my wits’ end.

Initially, I had the error message telling me that the .stfolder couldn’t be found, and now, the software lies and says the folder is up to date, but it’s really not syncing anything at all, and it’s not even creating a .stfolder.

See attached screenshots for more information, forgive me for the hasty phone pictures, I’ve spent hours trying to diagnose this and I’ve lost my patience

DESKTOP :

STEAM DECK :

The situation has evolved in some sort of way as now I get this lovely message

It looks like a permission issue to me, since it can deal with things outside of this folder alright, I’m not sure how to change those on SteamOS, can anyone give me pointers?

I can provide more information as needed.

I fixed it by installing the native version and not the flatpak one.
