Comment (by Tom-Bertin):

 Reinstalling Xcode CLT did the job!\\

 After reinstalling CLT, 'selfupdate' + 'upgrade outdated' started
 installing libgcc11 (which took hours!). This was the first time libgcc11
 appeared in a list of dependencies or ports that needed updating. After
 that everything seemed normal again.

 Thanks a lot for the great help!

 Best regards,
