### Godot version

v4.1.stable.official [970459615]

### System information

MacOS Big Sure 11.3

### Issue description

I got a bug report on my project and then did a deeper analysis to find the rootcause of Godot crashing on exit.
https://github.com/MikeSchulze/gdUnit4/issues/225

short story
- i removed all classes and resources step by step but still crashs at Godot exit
- finally i find out a simple print statement in the `func _exit_tree():` let the editor crash at exit.


### Steps to reproduce

Step one
- Create a new Project
- Create a new plugin over the editor provided plugin creation tool
- activate and exit ... works

Step two
- open the `plugin.gd` and add a print statement to `func _exit_tree():`

```
@tool
extends EditorPlugin


func _enter_tree():
	# Initialization of the plugin goes here.
	pass


func _exit_tree():
	prints("_exit_tree")
	# Clean-up of the plugin goes here.
	pass

```

- close/restart the editor is crashing at exit


### Minimal reproduction project

n/a
EditorFileSystemDirectory *efsd = EditorFileSystem::get_singleton()->get_filesystem_path(p_path.get_base_dir());
	if (efsd) {
		String file = p_path.get_file();
		for (int i = 0; i < efsd->get_file_count(); i++) {
			if (efsd->get_file(i) == file) {
				String type = efsd->get_file_type(i);
				if (singleton->icon_type_cache.has(type)) {
					return singleton->icon_type_cache[type];
				} else {
					return singleton->icon_type_cache["Object"];
				}
			}
		}
	}
	return singleton->icon_type_cache["Object"];
}
