And after almost a year I was finally able to install CU successfully with sconfig, I did exclude some folders from defender that might helped.
thank you so much for all your help and support I really appreciate it.
As someone that would never give up I tried a lot but nothing really that helped, basically after all issues was cleared with your help, defender might still be the blockage and update with sconfig on a server runs way smother and faster.
Again it worked only after we cleared all other issues, and for that I really appreciate.
