Best answer:
Remove any screen protector on place so that your finger is hitting the screen directly. If this works, then the screen protector is your problem.
Once removed or If you don't have a screen protector. Clear all Screen Locks completely, Pin, Fingerprint, Pattern and Facelocks etc
Also do a search for Biometrics as per the image below, and if its available, Clear the Biometrics Service App info Cache and App info Storage as well.
