after trying to update CiviCRM on my Joomla 5.02, first I got some errors when launching CiviCRM, now I cannot login my Backend as admin at all. (see related question: Installation (5.69.1) fails: Server 500 Error (Joomla 5.02))
This is what I'm seeing when I try to login as admin: https://i.imgur.com/CuFfNbd.jpg
Any help is welcome, because I can't do ANYTHING right now!!
