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!

EditorFileSystemDirectory *fs = nullptr;
	int cpos = -1;
	bool found = _find_file(p_file, &fs, cpos);
	ERR_FAIL_COND_V_MSG(!found, ERR_FILE_NOT_FOUND, "Can't find file '" + p_file + "'.");
	
	HashMap<StringName, Variant> params = p_custom_options;
	String importer_name; 
	if (!p_custom_importer.is_empty()) {
		importer_name = p_custom_importer;
	}
	ResourceUID::ID uid = ResourceUID::INVALID_ID;
	Variant generator_parameters;
	if (p_generator_parameters) {
		generator_parameters = *p_generator_parameters;
	}
	if (FileAccess::exists(p_file + ".import")) {
		
		Ref<ConfigFile> cf;
		cf.instantiate();
		Error err = cf->load(p_file + ".import");
		if (err == OK) {
			if (cf->has_section("params")) {
				List<String> sk;
				cf->get_section_keys("params", &sk);
				for (const String &E : sk) {
					if (!params.has(E)) {
						params[E] = cf->get_value("params", E);
					}
