Smart search, Facial Recognition not working anymore?

Hey guys!

Just reinstalled Immich to the newest version on CasaOS
I might messed up something in the setting but the machine learning stuff doesn't seem to work.
People have disappeared.

I have tried reinstalling again and again, reset the config many times, but so far nothing has improved.
Could it even be a bug? Do these features work for you?

Thanks in advance for your help!
