Research direction
Start with the access violation at packages/include/mikktspace/mikktspace.hh(119), then trace the mesh path through indra/llmath/llvolume.cpp at lines 2318, 2700, 2763, and 5687. Use the BugSplat report and its attachments to identify the triggering mesh; done means the reported mesh-processing crash is prevented and the affected path is covered by an appropriate regression check.
