Jitsi Meet not working anymore after updates

I’m experiencing something really strange after applying updates for UCS 5.
I try to keep the server up to date, but after some of the last applied updates, Jitsi does not allow the users to validate as hosts for the meetings, then not being able to open a meeting anymore. It keeps asking for the username and password all the time.
Did anybody experienced the same? Is there any solution for this?
Thanks, and best regards,
