Call to a member function loadArray() on null since update to Joomla 4

Hello,
i have no more access to configuration, see picture attached.
Joomla 4.3.4
PHP 8.1.24
OSM 3.4.1
Always get following error All other sections are possible, only Membership > configuration is not possible.
 

Hi together,
After I switched on the debug modus the error message was In Joomla 3 it was installed the rokpad editor which i have to uninstall before updating to J4.
Then I come to idea to check the OSM database table, maybe there is still the old rokpad editor.
Yep, that was the problem. I just removed the entry in the table to NONE and the error was gone.
   

Yes, that's right. The reason is because you configured Membership Pro to use a certain editor but that editor is not available anymore and it causes the issue

I'm glad you figured out

Regards,
