Touch ID randomly stops working

I just updated to Big Sur and the problem I am facing is that the Touch ID randomly stops working after I lock the screen and I have to enter the password instead of using the Touch ID to log back in. Any fix for this?


Thank you

I have the same issue, however Touch ID does generally work the first time the lock screen is presented. After that, it fails to register a correct fingerprint and I need to enter the password to get back into the machine. The Touch ID system does continue to work for things like Safari logon however.


This has only started happening after the Big Sur upgrade 2 days ago.
