Issue description

When I use Godot downloaded through the Steam on Steam Deck (Linux) it floods my project folder with lots of temporary files, is unable to run, and gives errors: https://pastebin.com/VFttvqcf. This doesn't happen when running the Godot Linux download on the website.

Steps to reproduce

Run the Steam downloaded version of Godot on Steam Deck and create a new project.

Minimal reproduction project (MRP)

N/A.

Saw this part in the log.

Cannot save file 'E:/steamapps/common/Godot Engine/editor_data/editor_settings-4.3.tres'.

Most of the the filesystem on the Steam Deck is read-only (it's an immutable distribution), but I don't see why Steam would be unable to write to the game-specific folder.

The Steam release uses self-contained mode, as indicated by the ._sc_ file present in the same folder as the Godot binary in the installation folder. You could disable this by removing the ._sc_ file, but if the filesystem is read-only, you may be unable to do that.

I tried removing the ._sc_ file and set the Godot Folder permissions for Owner, Group, and Others to "Can View and Modify" and made sure to apply it to all sub-folders, but it didn't work: https://pastebin.com/HAZBvYtR

Something else I noticed is if I verify the integrity of the game files, it restores the .sc file, so future updates may end up doing so also.
