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.
The Editor crashes.
The Editor launches successfully.
