Thank for reporting.
Does this file slice fine in previous versions?

The crash is caused by the empty first layer. Though it's weird that it doesn't crash on Windows. And on 2.1.1 it won't crash, but giving the correct error message instead:

Seems to be caused by this change.

Odd that it has an empty first layer. It prints on the Bambu slicer, and I used the "lay on face" tool to flip it just before slicing. Is the "lay on face" tool not placing objects all the way onto the bed?

I used “lay on face” before the slice/crash. Is “lay on face” not putting the object all the way down onto the printer bed?

It does.

In this scenario, the bottom of the model is shaped like a 'V,' so the first layer ends up being a zero-width line on the bed.
A few versions ago, Orca decided not to hide this issue with an 'auto-fix.' Instead, an error message is displayed to ensure users are aware of the problem with the model.

Since the 'auto-fix' function in BS or PS is still quite premature and unreliable, we believe it’s better to inform users about such issues directly.
