touch bar went black out!

Thanks.

Sometimes software wise, starting up in safe mode may help. This includes 2 restarts.

Hardware wise, resetting SMC may help.

The screen shot you posted is missing preference options.

From what I understood in the question, that is the point, they are saying that they are missing and that is why they posted them on here to show that they were missing.

I would suggest getting in touch with Apple Support and let them know what you have going on. They may be able to help you, but I imagine that they are going to have you take the computer in to have it looked at. I don't know why it is doing that other than maybe something went wrong during the update or there was some underlying hardware failure that just had perfect timing in that it went out when the update was going through. Again, get in touch with Apple support and have them walk you through some things that you can try.
