Good day! I'm Raniel, a Microsoft user like you. I understand your frustration regarding this issue and I'll do my best to help.
Just to clarify, did you make any changes to your machine before encountering this issue(like installing third party apps, recent updates, etc..)? Do you also encounter the issue when you access your account via safe mode?. Please see the steps under "From the sign-in screen": https://support.microsoft.com/help/12376/window...
Once in safe mode, aside from the SFC, kindly run the DISM commands as well to repair system files
- On the search bar, type "command prompt" and select Run as administrator
- Type the following commands in order
sfc /scannow then press Enter
Dism.exe /online /cleanup-image /CheckHealth then press Enter
Dism.exe /online /cleanup-image /ScanHealth then press Enter
Dism.exe /online /cleanup-image /RestoreHealth then press Enter
- Perform a clean boot and check again: https://support.microsoft.com/help/929135/how-t... and check again.

Go to C:\Users and delete the file with the same name as your user profile
If that didn't work, another option is to enable the built-in administrator account to isolate the issue
- On the Windows sign-in screen, press and hold the Shift key, then select Power > Restart
- After your machine reboots, click on "Troubleshoot" under Choose an option
- Click on "Advanced options" > select "command prompt"
- On the command prompt window, type
net user administrator /active:yesand press Enter - Reboot your machine, then login to your admin account, and check if you'll encounter the same issue.
Note: If you don't encounter the issue on the built-in administrator account, I suggest that you create a new user account (go through the steps under "My computer is in a workgroup") . Please refer to this article as a guide: https://support.microsoft.com/help/14039/window...
I hope this helps. Good luck!
