### 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

	cd->set_text(p_text);
	cd->set_ok_button_text(p_ok_text);
	cd->set_cancel_button_text(p_cancel_text);
	cd->connect("confirmed", callable_mp(singleton, &EditorNode::_immediate_dialog_confirmed));
	singleton->gui_base->add_child(cd);
	cd->popup_centered();
	while (true) {
		OS::get_singleton()->delay_usec(1);
		DisplayServer::get_singleton()->process_events();
		Main::iteration();

		}
	}
	memdelete(cd);
	return singleton->immediate_dialog_confirmed;
