Mac Book Pro 15" 2016 Touch Bar not working after Catelina 10.15.5 update

Hello sidjjw1996.

Thanks for reaching out to Apple Support Communities. I see from your photo that the Touch Bar on your MacBook Pro is not working. I will be glad to assist.

Here are some suggestions:

• Reset the SMC that puts power to the Touch Bar: How to reset the System Management Controller (SMC) on your Mac
• Just in case it's related to settings required by the Touch Bar, also be sure to reset the NVRAM/PRAM: Reset NVRAM or PRAM on your Mac
• To narrow it down, also be sure to check your Mac in safe mode: Use safe mode to isolate issues with your Mac You can also try a new user as well: How to test an issue in another user account on your Mac
  • If it only happens in your user and not in safe mode, try removing login items that might control the Touch Bar: Open items automatically when you log in on Mac
  • If it happens in both safe mode and a new user, back up your Mac and reinstall macOS using Recovery which will reinstall required information for the Touch Bar: How to reinstall macOS from macOS Recovery

If you're still having issues, it might be related to hardware. Here are the options for service: Mac Repair - Official Apple Support

Cheers.
