Crash when slicing with Arachne and small "Overhangs - threshold for - Bridge speed and fan"

[replaceitem]

What happened?

When slicing specific models, in my case this one (rotated upright), superslicer crashes during the "Generating perimeters" stage. Sometimes there is a split second where a popup briefly opens, saying "SuperSlicer has encountered a fatal error: "Access (status) violation", but it immediately closes with the entire program crashing.

Project file & How to reproduce

After resetting many options in my print configuration to default, i could narrow it down to a combination of two settings. When the Arachne Perimeter generator is enabled and the Perimeters & Shell > Overhangs > Bridge speed and fan is set very low (below around 23% for me).

Attached is a 3mf file, which upon slicing will crash superslicer. It contains a very small slice of the model, to which i narrowed down the layer that causes the crash. There is no crash_log.txt file generated. For easy reproduction, i used the default "Original Prusa MINI & MINI+" template, with only the "Max layer height" of extruder 1 increased to 0.4, since the print settings first layer height is by default 75%.
