NOTE: The project that I provided was picked up from my owner project. Sorry I can't provide a minimal reproduction project because I don't know which step cause this issue. I was test like this:
Create a project, import the glb file, create meshinstance and assign mesh, but there was not error!

EditorFileSystem *sd = (EditorFileSystem *)_userdata;
	sd->_scan_filesystem();
}
bool EditorFileSystem::_test_for_reimport(const String &p_path, bool p_only_imported_files) {
	if (!reimport_on_missing_imported_files && p_only_imported_files) {
		return false;

	if (!FileAccess::exists(p_path + ".import")) {
		return true;
	}
	if (!ResourceFormatImporter::get_singleton()->are_import_settings_valid(p_path)) {

	}
	Error err;
	Ref<FileAccess> f = FileAccess::open(p_path + ".import", FileAccess::READ, &err);
