My Mac's Touch Bar's display doesn't work near the Touch ID button, and I have no idea why. There is supposed to be a Siri button at that location, but it's not there.
The touch still works at the black area, but I hope the display isn't broken or something.
Tried Restarting and resetting the SMC, but it didn't work.
Device: MBP 2018 13-inch Touch Bar
OS: macOS Mojave 10.14.6

There are a couple processes that send data back and forth and this is a sign you need you log out of the user account so that those processes can exit and then when you log in, see if the connection is fixed.
Unless this is something that you run into very often, I'd log out and then restart to be sure it's not systemic before expending a lot if time digging into this.
