Task Manager hanging up is mostly likely there is a process at fault. Did you run sfc /scan now and go through the steps in the Dism Tutorial? Have you rolled back your system to a prior System Restore point, before this started?
I didn't go to a previous restore point, i saw the issue and rebooted but there is no difference at all
Try doing the sfc /scannow and the Dism fix. It will not cause any harm on your system, other than hopefully fix things. DISM - Repair Windows 10 Image - Windows 10 Forums
