Hi shahzaib3551,

To start, we suggest making sure your Mac is running the latest software version:

Update macOS on Mac - Apple Support

If you’re still unable to sign in, try booting your Mac into safe mode:

Lastly, see if the issue is present in a new user account:

Let us know the results.

Take care.

Hello, I have the same issue in my MacBook Air M1. I have tried all the proposed solution. Different user account, safe mode and I even rested everything and did an operating system re-install. Is there any solution to this problem?
