Upgraded to Mac Os 10.15 Beta and Fn key doens't work anymore

Hello everyone,

I just upgraded to Mac OS 10.15 19A501i on my MacBook Pro 15-inch 2016, and the Fn key doesn't seem to work anymore, it is completely ignored. I have played with the keyboard system preferences, but no avail, the Fn is literally dead. Any ideas? Am I the only one having this issue?

Macbook Pro 17
1. My touch bar is not showing at all after upgrading to 10.15. It was working fine before. I don't have any agent running for touch bar in activity monitor

2. I am unable to drag and drop any file from finder with three finger drag enabled or with the mouse click and drag.
