Cannot Login To Laptop After Latest Windows 10 Update

Hi all, basically, as the title says. My laptop had yet another several hour long update today and since it finished I can't login. At first I tried signing in the exact same way I have for about 3 years now only to be told my password wasn't correct. So I reset my password to something new. Now, I get the screen with my email emblazoned across it with the words Sign In underneath. When I click Sign In I get a big white Microsoft Account square with Enter Password etc which I have never gotten before. When I enter my new password I get prompted to new PIN. When I hit Next I get a screen saying Something Went Wrong. Hitting Retry gives the same result. Hitting Skip For Now seems to reset everything and bring me back to the original Sign In screen and it's just a never-ending loop. I simply can't sign in to my own laptop anymore. Anyone have any experience with this?? There are no options to change user and no options to use a different type of login, biometrics etc. Thanks.

Thanks for the suggestions Fabler, I have just tried restarting in Safe Mode and when I get to login and enter my password I am now getting a white message box saying "Search for app in the Store? You need to install an app for this task. Would you like to search for one in the store?" When I click on Yes, nothing happens 😭

I have also just tried to do a reset. I have chosen to keep my files but then when it asks me how I would like to re-install windows I choose Cloud Download and it just says "Unable To Download. Please try Reset this PC using the local reinstall option". The problem is I don't have any disc etc for Windows 10 to do this! Any ideas??
