FreeCAD 0.21.2 Linux x86_64 segfaults when trying to import Fusion 360 model

[Ghostbird]

Full crashlog is here

Summary

I tried to import this file, FreeCAD segfaults probably because of something that goes wrong in libTKMesh.

It fails regardless of whether I select nativ mode or conversion to STEP format.

On a current dev appimage with the posted file, the native import does not crash but it generates strange geometry that is not visible unless selecting parts and fitting the view to selection. Reopening the file (revert didn't work) and selecting "convert to STEP" seems to successfully build the model but segfaults in StepShape_ShellBasedSurfaceModel::NbSbsmBoundary() after a few steps. Log is here: freecad-appimage-0.22.0devR38385.2024-09-02.1112h.log

@Ghostbird better to work on development release 0.22.x (https://github.com/FreeCAD/FreeCAD-Bundle/releases/tag/weekly-builds)
