Mac OS sierra keystrokes dont work

Mac OS sierra keystrokes dont work even after I autorise in the pref panel
the app quit but when I luth again still not working

It’s now February 2008, I’m running High Sierra, and the keystrokes still don’t work.

I start Mouseposé, and it asks to turn on the “Control your Computer” setting in accessibility. It opens system preferences (although it has to try twice: once with a Boinx dialog, again with a system dialog). I give it the permission, but it is not persistent. It asks each time for keyboard support when you try to activate Mouscapé’s effects.
