NullReferenceException by RadGridView.LoadLayout

My current version is 2024.1.312.40

I tried to load a layout (xml file) saved in a previous version RadGridView and get an error that I cannot intercept. In which way I can either catch this exception or disable their occurrence for the user?

The exception occurs in the method: rdgvMain.LoadLayout(reader) and try is not working;

strLayout, reader, stream are not empty

 try
            {
                using (var stream = new StringReader(strLayout))
                {
                    var reader = XmlReader.Create(stream);

                    rdgvMain.LoadLayout();

                    stream.Close();
                    reader.Close();
                }
            }
            catch (Exception ex)
            {
                AddInfo(ex.Message);
            }
