Hi Jean-Pierre,
some time ago you have written:

This will not be changed. You have to define your
primary groups on Linux the same way as on Windows.
(Alternative : switch to Windows 8 or Windows 10).
Now I have a dual-boot installation with fresh Windows 10 and Ubuntu
20.04.
When running ntfssecaudit from Ubuntu, I get:

So I'm wondering, why your statement is not true here. Both users are
in the same Windows group, so I have the same mapping problem as with
Windows 7.
This is because you upgraded from Windows 7, and in the
process the local account parameters were preserved.
As your user groupings are not the same in Windows and
Linux, you cannot have a sensible interworking of ownership
and permissions.
As second problem is, that secaudit doesn't run through here (I had to
cancel it with Ctrl+C):
Now secaudit works again.
The reason for the error before seems, that
/mnt/Daten/.NTFS-3G/UserMapping was an empty file on my first try.
Looks like a bug...
Jean-Pierre
