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!

f->store_line("[params]");
			f->store_line("");
			
			List<ResourceImporter::ImportOption> options;
			importer->get_import_options(file, &options);
			
			for (const ResourceImporter::ImportOption &F : options) {
				String base = F.option.name;
				Variant v = F.default_value;
				if (source_file_options[file].has(base)) {
					v = source_file_options[file][base];
				}
				String value;
				VariantWriter::write_to_string(v, value);
				f->store_line(base + "=" + value);
			}
		}
		
		{
			Ref<FileAccess> md5s = FileAccess::open(base_path + ".md5", FileAccess::WRITE);
			ERR_FAIL_COND_V_MSG(md5s.is_null(), ERR_FILE_CANT_OPEN, "Cannot open MD5 file '" + base_path + ".md5'.");
			md5s->store_line("source_md5=\"" + FileAccess::get_md5(file) + "\"");
			if (dest_paths.size()) {
				md5s->store_line("dest_md5=\"" + FileAccess::get_multiple_md5(dest_paths) + "\"\n");
			}
		}
		EditorFileSystemDirectory *fs = nullptr;
		int cpos = -1;
		bool found = _find_file(file, &fs, cpos);
