Ok, Tried couple of things, updated moodle plugin and switched to PHP 8.1.. Now with CLI I can copy course, with GUI it stuck at 98% but you can see that course copied, still showing process. But when I try to delete that course, it is not deleting.. even tried deleting CLI copied course but it is stuck in loop of delete.. I was working in the sound blends group when this crashed - not problems before that. May be Question bank have issue with linking of new courses with question.. no error in CLI copy, I set debug mode to developer but not a single error I can see.. it is very confusing..
