Apple is impressing me with how determined they are that I quit using their products. I'm astounded that after all these year, they insist on screwing their things up so badly. So this is the last time I'm going to buy a laptop from them, ever again. I do not understand how can a laptop from 2016 that worked just fine before Big Sur, to run like a freaking dirty sock! You sock apple! Reaaaaaally bad! Not sinking money into your products ever again.
