When I try to add a new fingerprint nothing happens. I followed all the instructions I found, but it does not work - even formatted my Macbook Pro.

On an M1 Mac—equivalent Shut down, close the lid 30 secs+ , reboot as normal.
If no resolve try SafeBoot How to use safe mode on your Mac - Apple Support to sort anomalies.
