After a clean reinstall of OSX Catalina 10.15.2 on a MacBook Pro (15-inch, 2018), Esc button from the touchbar has disappeared.

I don't have any 3rd party tool or app installed.

Any idea on how to bring it back ?

After killing Touch Bar server application it will come back. Just paste the following to terminal and enter your password when asked:

sudo pkill TouchBarServer
