Opening MuseScore when Mac connected to Yamaha drums

I am not able to open MuseScore when my Mac is connected to the Yamaha DTX-452 drum set. Attached please find a pdf with error logs generated by my laptop.

Why is it a major issue for me? Because even when I have the MuseScore open, sound it's not going through Yamaha drums, just from laptop speakers (Yamaha is shown as 'speaker', Spotify, Youtube, many other apps works). So tried to close MuseScore an open. I am getting the same exception every time and it looks like MIDI.

Quick look at logs, and it looks like a problem related to 'PortMidi' library.

Since I am reporting here actually 2 bugs, should I create a separate thread for the second one (no sound going through chosen speaker<>)?
