Password entry casues screen lock?

[Android Central Question]

My phone (Moto z3) has a fingerprint sensor, but sometimes it doesn't work or I just need to enter my password (using the 9 dot thing).

Starting a few days ago, whenever I enter the password, the screen simply shuts off.

Any thoughts on where to even start with this?
