### Godot version

4.0.2

### System information

Windows 10

### Issue description

EDIT: this was fixed by removing the offending files listed with the MRP and then dragging them back in from my desktop after opening the project~

I was developing my game then suddenly this started happening. I can no longer playtest my game.
I am not 100% sure what caused this but I believe at the time I was making a new inherited scene, saved it, then moved some scenes in the FileSystem tab?
