UI is flooded by fingerprint failures
Fingerprint was always a bit voodoo on my ThinkPad (device messed or fingerprint mismatch). But I experimented several times on Fedora 38, an issue where the UI is flooded by fingerprint failures (a pill up of error messages below the login area). At the same time, there is probably a focus issue and the fact you enter the password nowhere. Thus, you have to fight with the UI to login. It could be it is due to the interference of several issues.
