Here is the file from step 3
The directory /var/crash is empty, or at least ls /var/crash/ does not
return anything.
There are some error reports, but just about onedrive and they are from
last year, so I doubt they are relevant for this problem.

Public bug reported:
I updated the machine yesterday, and additionally added the fingerprint
to pam using pam-auth-update. The screen now stays purple after logging
in using the finger, but works fine after logging in using the password.
