MIDI input from Casio Privia PS-160 does not work in Dorico 3.

My Casio Privia PX-160 has played sometimes in Dorico 3, but other times there is NOTHING I can do to get the keyboard to register notes in Dorico 3. When it has worked, the lower right corner showed the notes and the notes came up on Dorico. Now neither happens. What is stopping the MIDI input into Dorico 3? I know the connection is there and it works on other software. Edit-Preferences-Play shows the Casio keyboard present. I’ve deleted the driver and it reinstalled on the computer, but still won’t come up in Dorico 3.

Could you please do Help > Create Diagnostics Report? That creates silently a zip file on your desktop, please attach that here. Thanks
