Touch Bar has stopped working after reboot

The Touch Bar of my MacBook Pro (15-inch, 2019) with Mojave 10.14.5 has stopped working. It still displays information and its display changes when I change apps but nothing happens when I try to press the bar virtual buttons. The problem started after a reboot. Further reboots haven't fixed the problem.

I have read that it is possible to refresh the Touch Bar by manually killing the “Touch Bar agent” process. I do not know if it is linked to my problem but when I look at the Activity Monitor, I cannot find any Touch Bar agent.

Any hint?

Thanks, I tried both 'sudo pkill TouchBarServer' and 'killall ControlStrip' as suggested. In both cases, the Touch Bar turns off and then back on but the problem remains. The virtual buttons are still irresponsive. Could it be a hardware problem?
