Touchbar dead after OS 27 upgrade

Touchbar dead after upgrading to OS 27, had same issue with OS 26, but resolved by rebooting several times, this time unfortunately without any success. It though flashes during booting and at start up!! So the touchbar is not dead, but seems to have some software bugs? Any help or clues?

Solved, I made several hard boots (pushed down on/off key until reboot possibilities appeared), and suddenly it worked

Thank you very much. I had exacly the same on my MacBook pro M1. Just after updating to OS 27.0.1

Fixed with hard boot (hold on TouchID until the mac stop)
