Windows 10: Unable to login using MS account after updating to Win 10 build 19042 - no errors displayed

I have been using Win 10 on my PC for years & logging in using my MS account.
I updated to build 19042 yesterday whilst logged in with my Microsoft account.
At the end of the update I was asked to reboot.
When the login screen re-appeared I was not able to login with my Windows account. I entered the correct password then switched to try my PIN.
I did not get an error using my password or pin - the screen flashed briefly then returned to the blank front screen displayed prior to clicking the mouse to see the login dialog.
I have a local user admin set up on my PC and am able to log in as that user.
I checked for further updates and applied them 2 of them in case it was a known issue but to no avail.

I have researched for the past day how to get over not being able to get into the PC using my Microsoft account but everything I have tried so far has failed.

NB: If I set the PC to Safe boot I CAN log in using my MS account, it finishes off the update from yesterday then displays my user home screen.
NB: I can log in using my local account then log into my MS account online. I believe this proves there is no damage to my MS account.
NB: I created a restore point prior to updating to build 19042 but this has been deleted as have all restore points prior to the update.
NB: I do not particularly need/want to log in using my MS account but was forced into it originally and now have that user set up in the way I want and I do not wish to waste more time setting up a different user and getting them set up the same way and trying to copy over years of data from multiple applications.

Login not accepted for my MS Account

Let me explain, again, what I have experienced:

• I use my MS account to unlock this computer. No problem doing that
• I attempted to use other apps requiring the MS login, like Outlook, or even this forum, and it would not accept the very same credentials I used to unlock the computer
• I used my wife's MS account to login to this forum so that I could seek help
• I have tried resetting my MS account twice, and that did not work either.

I would appreciate suggestions OTHER than wha I have already tried

 

Can't sign in with MS account in Win 10

Thanks, this was not my fault or mistake. I just switched to local account from MS account. It's very simple to back again to MS account. It's a fault of MS insider build. Afterall I tried as per your suggestions. My existing MS account is not removing from
the list. Taskbar start menu not working. Very bad situation. I can't get further updates.

Any other help plz.

 

Cannot login to windows 10 after update! PLEASE HELP!

Thank you for the advice on enabling the administrator account. I follow all the steps and enabled the administrator account but I am still unable to log in. I am attaching 2 photos of the screens I am able to see at boot up.




I have no way to choose which account to log in with.
Any other ideas or suggestion?
Thanks
