[Problem] Hard Crash while idle and in background, v0.21.2-33771 on MacOS

Is there an existing issue for this?

Problem description

While the program is idle, and in the background (possibly while my machine was even with screen saver showing - not sure), the app crashes, and creates an Apple Crash Report (attached zip).

File being edited is attached, zip.

I wish I could give more steps, but that is it. Has repeated a couple of times in the past few hours.

I think it was in the Part Designer workbench.
