After disabling them, open Windows Defender and check if the problem persists. If Defender is still not starting, follow the steps in method 2.
- Type “run” in the search box that appears when you click on start button, then type “services.msc” in the “open” search box,and press Enter.
- In the window that appears, navigate to Windows Defender service in the list.

right click on the Windows Defender service and then select Start.
