I have MacBook Pro 16" 2019 model. Just updated to Big Sur on Nov 27. Since the update every time I close the lid, the laptop shuts down abruptly. It takes forever to turn it on again and it shows sleep wake failure error. It's been happening quite often now. I tried NVRAM reset, reinstalling the OS as well. But the problem still persists.
