• Since upgrading to Big Sur, the Touch Bar is completely busted....

No matter what programme I open, the Touch Bar icons never change. They only show Brightness, Volume and Mute Volume, with the expand icon.

• If I tap the 'expand' icon on the Touch Bar, it expands to show all the icons but then the entire Touch Bar goes blank....

Customize the Touch Bar on Mac - Apple Support

make some changes to see if it responds.

I was part of the Big Sur Beta. I wiped my Mac then did a clean install of Big Sur when it was officially released. It is all working fine now.

Thanks for clarifying your issue— any the final resolve.
