Hi Rajesh Sortur,
Since Windows is asking you to set up your PIN again, the issue may be related to the account used to sign in rather than the laptop itself.
If you cannot access the account because the recovery codes are not arriving, use Microsoft's account recovery process as suggested by AI answer and check whether you have any alternate recovery email addresses or phone numbers associated with the account. If the Yahoo email address is also inaccessible, any previously configured recovery method may help restore access.
If no sign-in method works, you can try Startup Repair or System Restore from the Windows Recovery Environment to see if Windows can recover the sign-in configuration.
Should the account recovery process continue to fail, it would be best to contact Microsoft Support for further guidance on available account recovery options.
