Windows 10: Account Not Appearing at Sign In

I have an M365 account that is no longer appearing as a user that is able to login. This has happened after the October 2020 Feature Update - 2OH2. I can see the profile under Users, but don't see it as a sign-in option. Do I have to add the account again and will that mess up syncing? Why did this happen?

Desktop appears from different signed-in account


I noticed after a Windows 10 repair install that the desktop that appears isn't the desktop from the user account with which I'm signed in. In fact, that user account is no longer listed in user accounts, but its files still appear in C:\[my computer name]\Users. How do I get the correct desktop to appear?

 

Cannot sign in microsoft account.

My device: Lumia 520. GDR2.
I cannot sign in my Microsoft account on my device. It didnt say any error but Microsoft account is not listed in Email and account list. When I click add button, it will show microsoft account option but after press sign in, it is still not shown in email
and account. Another problem is i cannot delete facebook account. Error code: 0x83cf1202. I have tried as suggested here: http://support.microsoft.com/kb/2475837/en-us#step0x83cf1202 but as my Microsoft account is not shown, I cannot do step 6.

Any suggestion?
