PrusaSlicer crashes during slicing

[MrQuallzin]

Description of the bug

In the past couple days, PrusaSlicer has started crashing during slicing, even on simple models. I haven't made any major changes that I'm aware of, and am unsure what would be causing this. It seems to crash when Slicing Progress is at 70% (Generating Support Material) even if there is no support material to generate.

Project file & How to reproduce

WednesdaySign.zip

To reproduce, open the file and attempt to slice.

Have you tried Beta-2 yet? It was released today. https://github.com/prusa3d/PrusaSlicer/releases/tag/version_2.6.0-beta2

[MrQuallzin]

Just downloaded and retested, the error persists at the same slicing percentage.

I tested this with PrusaSlicer 2.6.0-b2 on my MacBook Pro (M1) running macOS 13.3.1(a). If I import just the model from the 3MF, it slices correctly and quickly. If I import as a project, it fails shortly after I start to slice. Here is the first bit of the crash dump:
