I had the same experience. Updated the computer, rebooted into the blinky screen. Powered off the machine & went to the BTRFS snapshot created immediately before my update. No damage to the screen that I'm aware of.

oh, I didn't think to try the btrfs snapshot route, that's a good idea to keep in mind for me if this happens again.
