Editor crash when trying to launch on an Android target device from a Mac native platform

The one time it did not instantly crash after pressing the Launch button, I had to Kill -9 <PID> UE4Editor because it was using 129% of my CPU for 50 minutes.

Repro:

1. Create a code project using a first person template without starter content.
2. Connect and Android device to the Mac computer and select Launch targeting the Android device.

Result:
Editor crashes.

Frequency:
5/6
