Hey There,
After I updated my MacOs to Big Sure It stopped functioning it shows me in the touch bar that it going up and down but nothing happening on the screen itself.
I tried reinstalling Catalina and it worked. but once I update it to the latest version which is Big Sur 10.6 it stops working.
Please I searched everywhere for the solution but none helped me.

On an Intel Mac you can try —
resetting the SMC https://support.apple.com/en-us/HT201295
resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
(get at least two-three rounds of the chimes when holding the NRAM Reset)
I tried This but it didn't solve my problem. :(
Brightness adjustment doesn't work since I updated my MBP 2017
