Since CIQ 3.2.2, simulator no longer starts on OS X (Catalina 10.15.6)

After updating to CIQ 3.2.2, I can no longer start the simulator on OS X (Catalina 10.15.6)

I've tried launching from the command line, but get no feedback whatsoever. No errors, no messages, nothing.

Can anyone suggest how I can track down the issue. (It worked fine at 3.1.9)
