-- END OF BACKTRACE --

I have yet to find out what exactly causes this. The project opens fine in 3.2.2.

Minimal reproduction project:

Coming soon (unless someone figures this out from the backtrace)

Probably related to #32428, CC @willnationsdev.

Turns out a reproduction project isn't necessary. The editor crashes as soon as you select a node with a script attached 🙃

[KoBeWi]

Ok, I know what happens. This is what causes crash:

godot/editor/editor_inspector.cpp

Lines 2439 to 2441 in c95fbd5

	Ref<Script> s = ResourceLoader::load(path, "Script");
	List<PropertyInfo> props;
	s->get_script_property_list(&props);

The script is loaded from a path, but when it's built-in, the loading fails because there's no path. Then a method is called on an invalid reference.
