No keys assigned in on screen keyboard

The on-screen keyboard does not seem to be working on Cubase Pro 10.0.10. iMac 2017 with Mojave 10.14.2.

It works with mouse click, but I want to use it with my keyboard.
It seems like keybinds are not assigned properly.
Does anyone else have the same problem?

Hi and welcome,

Are you on Mac or Windows? What language/keyboard do you use? Could you try in Cubase Safe Start Mode, please?
