Cannot add new shortcut or gesture

Describe the bug
I click on "new shortcut" (keyboard) and nothing happens. Attempts to add gestures for the trackpad or magic mouse show the gesture selection screen but any attempt to select a particular gesture will reset the interface and cause the new gesture button to reappear. I have followed the accessibility steps per at least 10 times. I have also uninstalled BTT using CleanMyMacX 5 times and reinstalled from Setapp.
