Sonoma: Macbook Pro (M1 2020) Touch Bar is not working after update (Flickers during restart then once logged in, it disappears)

I upgraded to Sonoma yesterday on my Macbook Pro (M1 2020). Touch Bar keeps flickering during startup (looks like it is glitching) then once logged in, it disappears. What could be a issue?

Tried safe mode, tried sudo pkill from terminal, and everything else online.


Could this be a hardware failure because of Sonoma?




MacBook Pro 13″, macOS 11.1

I upgraded to Sonoma and experienced Touch Bar strobing after upgrade. I reinstalled it again thinking I had a bad build. After fresh install, Touch Bar strobed until it went dark. Now I don't have an escape key which is irritating. I've tried everything online to fix it to no avail. In addition my activity monitor crashes every time I open it!
