Need help with Musescore 2.3.2 cannot playback with JACK Audio Server

• Jul 8, 2019 - 11:58

Problem:
- Playback is impossible on Musescore 2.3.2 with any of the pieces, music, song.
Attempted Solutions and all of them failed:
- Revert to factory settings.
- Reinstall Musescore.
I really wanted to use Musescore 2.3.2 because it allows the use of the JACK audio connection kit. But after some time of using, the playback of Musescore when having Jack audio server on no longer works. Is there something that I did?
Programs used for Jack audio server:
- Musescore 2.3.2
- JACK Audio connection kit
- Carla
- Kontakt 5.5.0
Things I have notice:
- Musescore Preferences > I/O > PortAudio => Musescore works fine.
- Musescore 3 works fine without JACK.
