PrusaSlicer crashes when left in background on Mac

[Bom342]

Version

Version 2.3.3+x64

Operating system type + version

OS X 10.14.6

3D printer brand / version + firmware version (if known)

Prusa MK3S

Behavior

Several times I have walked away from the computer and, when I come back, PrusaSlicer has no window. The program is still running, and I can quit and reopen, but if I tell the sidebar to Show All Windows it says there are no windows to show.

Project File (.3MF) where problem occurs

It is not file specific.

I guess this is now outdated. It was most likely fixed already, could be e.g. the same as #10890. Closing.
