A search on "The data at the root level is invalid. Line 1, position 1." will show you what a long history this bug has had.

The code shown is the serialize code that causes errors in deserialization. And, if the file does not exist, I do want it to be created.

Those (future) read errors (after more writes to the same file) can be prevented by deleting the file in the serializer prior to writing:
if (File.Exists(path1))
{
    File.Delete(path1);
}
Excerpt from deserialization code:
try
{
    using (Stream stream1 = new FileStream(path1, FileMode.Open, FileAccess.Read))
    {
        stream1.Position = 0L;
        TheData1 = (Data1) dcs1.ReadObject(stream1);
    }
}
catch (Exception ex)
{
    MessageBox.Show($"{path1} cannot be read");
    return;
}
I trust you (if not you, who ?) to have further insights Smile | :)
