Windows 10: Failed sign in attempt when it’s not an incorrect sign in

Unable to sign in due to incorrect pin and shutdowns Not true . I know my pin and did not shutdown incorrectly This started yesterday just randomly . I waited 2 hours to login . This morning the same Microsoft error . Please fix . I cannot work because of this .

:)

 

"This sign-in option is disabled because of failed sign-in attempts or repeated shutdowns" but why?

"This sign-in option is disabled because of failed sign-in attempts or repeated shutdowns. Use a different sign-in option or keep your device powered on for at least 2 hours and then try again" This message comes up almost everytime laptop is turned on, it hasn't had incorrect pin put in or any failed sign in or repeated shutdowns. The laptop only has pin or fingerprint options to sign in and it won't allow either without waiting 2 hours which is veri impractical. Is there a way to stop this happening?

It's an hp laptop, I think it's windows 11

This sign in option is disabled because of failed sign-in attempts or repeated shutdowns

I switch on the computer and put in my pin code. I get the message ' This sign in option is disabled because of failed sign-in attempts or repeated shutdowns. Use a different sign-in option or keep your device powered on for at least two hours and then try again'. The computer uses Windows 11. I've spoken to Dell who say it is a Microsoft issue, but I don't know who to contact and the troubleshooting page on Microsoft doesn't help either. This first happened two days ago. After keeping the computer powered on for two hours I was able to sign-in. Having switched off the computer at the mains, I am now unable to sign-in again today. Any suggestions would be gratefully received.
