Hi, good day! I'm John Dev a Windows user like you and I'll be happy to assist you today. I know this has been difficult for you, Rest assured, I'm going to do my best to help you.
Restart your computer, just as Windows attempts to load (spinning dots), press and hold the Power Button for 5 - 8 seconds or until it performs a Hard Shut Down
Do this 2 - 3 times until Windows will boot into the Recovery Environment
Select Troubleshoot > Advanced Options > Uninstall Updates
Uninstall latest quality or feature update
Select Troubleshoot > Advanced Options > Startup Repair
If this doesn't work, Select Troubleshoot > Advanced Options > System Restore
Select the restore point at an earlier date where everything is still working.
Click Next then Finish
Kindly let me know if this helps or if you have any further concerns.
Kind regards,
