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, 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...
Since you encounter the issue after a recent update, you may uninstall that update and check again(see the 5th or 6th method). Here is a guide: https://www.tenforums.com/tutorials/5486-uninst...
Once uninstalled, kindly use this tool to prevent it from installing again: https://www.tenforums.com/tutorials/8280-hide-s...
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...
If that didn't work, see if you'll be able to perform a system restore using the methods on this article: https://www.tenforums.com/tutorials/4588-system...
I hope this helps. Good luck!
