This can happen if users somehow got wrong user permissions assigned to their Godot cache, config or data paths (e.g. `~/.config/godot`). The error messages should give them a hint as to what the issue may be. Fixes #33199. There may be other situations that still lead to a crash, we need to review all uses of `FileAccess::open` with `FileAccess::WRITE` mode to ensure that proper pointer validation is done.
