Hello to everyone
I had the same problem when I upgraded from jellyfin 10.6.4 to 10.7.0
My workaround was to uninstall jellyfin
yunohost app remove jellyfin --debug
Then
apt list --installed | grep jellyfin
apt purge jellyfin-*
apt autoremove
And reinstall jellyfin
yunohost app install jellyfin --debug
