MacBook Pro M5: Missing Touch ID for restored user

This is a brand new MacBook Pro M5 to replace an older MBP M2 that suffered liquid damage. I restored it from the latest Time Machine backup, and everything works fine except that the Touch ID setting is missing from System Settings.

Thinking it was an OS issue, I wiped the laptop clean and set up a new user, and Touch ID shows up fine in System Settings, and I can create a fingerprint that works fine.

However, when I restore the user from the Time Machine backup, that user (which is an admin user) does not have Touch ID present in System Settings. It is missing completely.

The old MBP had Touch ID and that user worked fine with Touch ID. Does anyone know how to reset the Touch ID settings for the restored user and return it to System Settings?

Can you confirm this is the internal keyboard only— no external keyboard involved.

You have shut down and restarted more than once...?

Try A SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Does a quick disk repair before it fully boots up, and certain system caches get cleared and rebuilt, third party system modifications and system accelerations are disabled temporarily.

Login and test. Reboot as normal and test. Caches get rebuilt automatically.
