My Touch Bar on my 13" 2019 MacBook Pro works, but about 2 ½ inches on the right are invisible. Pressing the fn key shows up to F9, but is blank after that. Pressing in the F10 area works, but I can't see it.
I have tried resetting the SMC to no avail. I also tried customizing the strip via the Keyboard preferences also to no avail. The problem did not occur until I upgraded to Monterey OS, 12.0.1.
The best you can do is both—
Try resetting the SMC https://support.apple.com/en-us/HT201295
Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
(get at least two-three rounds of the chimes when holding the NRAM Reset)

If this does not sort your issue—it may indicate a hardware issue.
