Attempt to assign property "app_id" on null

[chris-m87]

I have JooAg Shariff on Joomla 4.3.3 and PHP 8.2 installed. It is also up and running there. But when I now want to add a new category or a new menu item, I have received the following error message during the saving process: 0 Attempt to assign property "app_id" on null How can this be fixed again?
