Superslicer crashes during model slicing. Using version SuperSlicer_2.5.59.13_2024-07-01 does not crash but reports the following error:

Is this a new feature request?
No.

Setting Thin walls = false stops SuperSlicer from crashing on 2.5.59 builds. The issue is prevalent in the app image build and windows build. The 2.5.59 builds are more graceful and display an error, while the 2.5.60 builds crash.

I also get regular crashes using 2.5.60 on debian sid. Clicking generate in the bed levelling calibration dialog is enough to reproduce, it appears to happen at the slicing stage.

This still happens on my system if I disable Arachne and Thin Walls. Running a backtrace in gdb gives me:

2.5.60 crashing for me on Mac every single time. Might be similar reason. Thin walls doesn't make any difference.
It starts to slice and crashes around, what looks like, beginning of infill calculation.

2.5.59-13 slices perfectly (same profiles used)
