Try this, as it worked for me to get rid of the finger print error.
Open Device Manager
Click on Biometric Devices
Click on Validity Sensors
Click on the Driver tab
Uninstall the Driver
Restart the Computer
Restore Windows to an earlier point in time.
The finger print login should now work
This approach to reinstalling the Driver is necessary, as after you Restart the computer, after uninstalling the Driver, the Biometric Devices icon no longer shows up in the Device Manager, so there is no otherway that I know of to reinstall the Driver other than to Restore Windows to an earlier point in time.
