One thing you can try, a system restore to a time just before the issue began.
If you have the bottom toolbar on the screen:
Click an empty portion of the toolbar, choose Task Manager/Applications tab/New Task.
Type in rstrui, then OK.
When the restore folder opens, click the icon named rstrui
System restore will open, choose the first option, click Next.
Choose a restore point-click Next. Your computer will reboot. After you reboot, you will find out if the restore was successful.
edit to add: if it works, you may find out when you reboot and the process is normal.
