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!

				if (assign == "source_file") {
					source_file = value;
				} else if (assign == "dest_files") {
					dest_files = value;
				}
			}
		} else if (next_tag.name != "remap" && next_tag.name != "deps") {
			break;
		}
	}
	if (importer_name == "keep") {
		return false; 
	}
	if (!found_uid) {
		return true; 
	}
	Ref<ResourceImporter> importer = ResourceFormatImporter::get_singleton()->get_importer_by_name(importer_name);
	if (importer.is_null()) {

	}
	if (importer->get_format_version() > version) {
		return true; 
	}
	
	String base_path = ResourceFormatImporter::get_singleton()->get_import_base_path(p_path);
	Ref<FileAccess> md5s = FileAccess::open(base_path + ".md5", FileAccess::READ, &err);
	if (md5s.is_null()) {
