Steam Deck, can't save edits file in use, locked, lacking permissions

[Dragon3025]

I'm on the Steam Deck trying to edit my game. When I open it, it says that I'm unable to write to "project_metadata.cfg", "script_editor_cache.cfg", and "editor_layout.cfg" because file is in use, locked, or lacking permissions.

When I try to save it says "Safe save failed. This may be a permissions problem, but also may happen because you are running a paranoid antivirus. If this is the case, please switch to Windows Defender or disable the 'safe save' option in editor settings. This makes it work, but increases the risk of file corruption in a crash.", but I'm using Steam Deck which runs on Linux.

This is a Windows specific error message, it would never be shown when using Godot's Linux version.

So it sounds like you're using Godot's Windows version via Proton, instead of the Linux build? If so I recommend switching back to the Linux build, there's no reason to use Proton for Godot.

@Akien: Thanks, that fixed it. Weird because using Proton was the default. I had to enable compatibility mod and switch it to Linux.
