The error message is telling you it cannot fix a user problem because
it expects the user to be a member of Domain users, which it is, but
in the wrong way.

I have been saying for sometime 'Do not change a users primaryGroupID
attribute'. I now have proof it is definitely not a good idea.

Where to go from here ?
I suspect you are going to have to undo what you have done and find
another way of doing 2 factor authentication.
