Had no issues upgrading your sites to 6.x before today. This one particular has all 3rd party extensions disabled except for yours!!!!, the latest template PITECH build and the latest pagebuilder ext is installed.. when i disable the backwards compatibility plugin as instructed by the Joomla upgrade system, the entire admin and site goes down. I fix that by going to the phpadmin and reanabling the plugin via the table structure.. everything comes back up fine.. I go back to the Joomla admin and start over, the same thing happens..all extensions are up to date.. no imcompatible extnsiosn are enabled.. and the same things happens over and over and over...is s never ending loop and yes im on php 8.3

what can help now?
