just got after compiling the Source in Visual Studio 2022 this Error.

Any Idea what can i do?

public void ReadXML()
        {
           
            if (!File.Exists("files.xml")) { return; } //if not exist return
            creatTable();

            using (XmlReader reader = XmlReader.Create("files.xml"))
            {
                reader.ReadToFollowing("critical");
                DataRow Row;

                do
                {
                    Row = downloads_info.NewRow();

                    reader.MoveToFirstAttribute();
                    Row["path"] = reader.GetAttribute("path");
                    Row["hash"] = reader.GetAttribute("hash");
                    Row["size"] = reader.GetAttribute("size");

                    downloads_info.Rows.Add(Row);
                } while (reader.ReadToFollowing("critical"));
            }


            calc_downloads();
        }
