Touch ID doesn't work on MacBook Pro 2019
I was going to take my laptop to repairs but accidentally discovered the offender is my LED desktop lamp. My laptop usually sits on a stand and there is a desktop lamp shining right on the keyboard from about ~50cm. If I turn the lamp on - Touch ID stops working, if I turn the lamp off - it does work flawlessly. It seems like bright LED light shining on my finger somehow interferes with Touch ID sensor. Go figure!
