JIT process stopped responding - Mac OS Mojave

Hello. New user here, working through some tutorials.
Mac OSX Mojave 10.14.6. JUCE 5.4.4

For example, from Projucer, with an unmodified “HandlingMidiEventsTutorial”, using the “Launch Application” button to launch the app displays a bunch of Active Sensing messages from a connected MIDI keyboard, and then it crashes (spinning beachball) and displays in the Projucer “JIT process stopped responding.”

If I “Save and open in IDE” (XCode 10.3), I can build it and run it and it works fine.

I also had this problem with the “MidiMessagTutorial” - launching it from Projucer would crash when you moved the Volume Slider to generate a bunch of controller messages in the list window. Running it from XCode - no problem.

Any ideas on how to fix this? Thanks.
