Big Sur - randomly goes screen to black.

Hey Guys,

After update to Big Sur I have a quite annoying problem which I temporarily fix it.

I have MacBook Pro 2019 with Touch Bar. And the problem is , that my screen goes randomly black three times or four times etc. when I am working in Safari, watching Netflix or whatever I am doing on Mac. And is repeat couple of times per day + battery going faster drain than before Big Sur.

So I have to couple of times , each day close my Mac and again open and after that screen goes on .... so I am tried restarting NVRAM, SMC, Safe mood all without solution but? One I found myself after days. Problem is with True Tone and Night shift it must be off and after that, is everything fine ( so at first maybe it helps someone ) but does anyone have experience with this? How it can run with True Tone and night shift without problem? I asked apple support, and there is no help, they didn't helped me at neither.

Thanks

Tomas
