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!

fc.uid = split[2].to_int();
					fc.modification_time = split[3].to_int();
					fc.import_modification_time = split[4].to_int();
					fc.import_valid = split[5].to_int() != 0;
					fc.import_group_file = split[6].strip_edges();
					fc.script_class_name = split[7].get_slice("<>", 0);
					fc.script_class_extends = split[7].get_slice("<>", 1);
					fc.script_class_icon_path = split[7].get_slice("<>", 2);
					String deps = split[8].strip_edges();
					if (deps.length()) {
						Vector<String> dp = deps.split("<>");
						for (int i = 0; i < dp.size(); i++) {
							String path = dp[i];
							fc.deps.push_back(path);
						}
					}
					file_cache[name] = fc;
				}
			}
		}
	}
	String update_cache = EditorPaths::get_singleton()->get_project_settings_dir().path_join("filesystem_update4");
	if (FileAccess::exists(update_cache)) {
		{
			Ref<FileAccess> f2 = FileAccess::open(update_cache, FileAccess::READ);
			String l = f2->get_line().strip_edges();
			while (!l.is_empty()) {
				file_cache.erase(l); 
				l = f2->get_line().strip_edges();
