Description

There has been a report of a consistent crash of the binary Editor on launch when it is being launched on an iMac Pro.

Additional information from two separate reports about this crash seem to indicate that input devices connected to the computer are providing axial input during launch that is causing the crash. An internal repro appears to confirm this.

This does not seem to be limited solely to iMac computers.

Steps to Reproduce
  1. Make sure an input device capable of providing axial input is connected to the computer.
  2. Adjust the input device to ensure it is providing axial input (eg. push a controller thumbstick in any direction and hold the input).
  3. Launch the Editor from the Launcher.

RESULT:
The Editor crashes.

Expected:
The Editor launches successfully.
