fprintd/fprintd-pam causes passwordless screen-unlock

Hello,

I’ve installed version 13.2 with all updates. I’m facing a seemingly unimportant problem. Whenever I lock the screen or it locks automatically, it will unlock without a password. After going through the logs, it seems that fprintd/fprintd-pam was the source of the problem. I’ve removed the packages and the issue doesn’t persist. However, I would like to have a real fix to this issue. Can anyone guide me on getting this resolved?
