Fingerprint settings completely missing

I've had my nexus 5x since it came out and fingerprint unlock has always works. That is, until a couple of days ago. Now the sensor doesn't work at all (doesn't even vibrate at all when touched). Also, I can't even find the fingerprint settings in the settings menu at all. It seems to have completely disappeared. Anyone else with similar experience or suggestions?

I have tried a reboot, but didn't do anything. Any further suggestions?

I'm running stock android, unrooted with all the latest updates.
