After updating the software, when you turn on the computer, the keyboard does not work correctly. Is that how it should be?

Question

macOS

Yesterday I installed the High Sierra 10.13.6 software update on my macbook. I noticed that now when you turn on the mac, the keyboard backlight stopped working. And in general, some oddities are observed during authorization. For example, it writes that the caps lock key is pressed, but in fact it is not.
