Playlists disappeared after the update

[pixel24]

Hi all,

The topic of playlists in Jellyfin is really a drama! I have just installed an update from 10.8.13 to 10.9.6 on an Ubuntu server (24.04-LTS).
Since the users are in an LDAP/ADS (Univention), I had to remove the LDAP plugin after the upgrade and then reinstall it. Otherwise, it was not possible to log in as a user.
After that, I was able to log in as a user again, and my favorites were also present. However, no playlists are being displayed anymore :-(
On the JF server itself, all playlists are present in:

Code:

/var/lib/jellyfin/data/playlists/

What do I need to do to have them displayed in the web UI again?

with best
