I went in last night and erased the HD an installed Catalina. Maybe when this is resolved I'll try Big Sur again.

It would be really nice if they released an update since so many people are affected. I put in a ticket in the fb assistant but nothing.

I tried installing a fresh copy, as I'm experiencing the same as all of the above. A fresh install did not help.

Same here. I have tried all of my bag of tricks but so far only running in safe mode to on to research the problem. All of these betas have been flawless. Hope they release an update soon.

Same. Updated now in kernel panic loop
