Touch Bar disappeared completely after Catalina update 10.15.5

I updated Catalina to 10.15.5 yesterday night and after that my touch bar gone black. Nothing is working except the Touch ID.

All the options available in the keyboard disappears as well. It is something like I didn't have a touch bar in my Macbook Pro 2019.

Googled a little bit and perform the proposed solutions.

1. Killing Touch Bar Server / Agent / Control Strip
2. Reseting the NVRAM
3. Reseting the SMC
4. Run Apple Diagnostics - Showing no Error (APD000)
5. Reinstalled Mac OS - Twice once keeping data and second time formatted whole drive.

Nothing works ;( ... Any help is appreciated.
