Hello, thank you for reaching out to Microsoft Q&A.
Do a System Restore or Startup Repair method from the Windows Recovery Environment and see if you can sign in with your password.
To boot your PC in the WinRE:
- Start your device and wait for the Windows logo (or the manufacturer's logo) to appear.
- As soon as the Windows logo appears, press and hold the power button until the device shuts down.
- Turn your device on again and repeat step 2.
- Turn your device on a third time. Windows should display the Automatic Repair screen.
Select Troubleshoot > Advanced Options > System Restore.
This option takes your PC back earlier point in time.
Once the system restore is complete, try signing in with your password. If the issue persists, try the Startup Repair method from WinRE.
Let me know if you still need more help.
