Jamkazam app crashes on startup

Did you ever get far enough that you had set up your JK audio settings to use the Focusrite for I/O? Maybe try unplugging the Focusrite, launching the app, then quitting it again, and re-connecting the focusright and see if it will launch and let you set up again. I'm running it on Catalina, but also had older versions running on a different laptop on Mojave.
