Win11 sub on Reddit is exploding with the issue and MS has not even acknowledged it nor released any hotfix yet. It's as bad as embarassing.
In one of the "tech" websites it was mentioned that MSFT is aware and the hardware manufacturers are testing this. Drop an egg on reddit and they would not even know how to bake it
It's not listed in any official bug tracker for now so, no, they didn't "officially" acknowledged it yet. All the rest is PR talk for (literal) damage control atm
In a recent past, Microsoft Updates crashed many machines around the globe, and even airports have been closed, so, I am not surprised at all
