Blender Version
Broken: 3.1.0 / blender-3.2.0-stable+v32.e05e1e369187-linux.x86_64-release

Short description of error
An object imported from I don't know where, with crazy material_index : (-30086) in spreadsheet editor, and with strange normal, makes blender sik.

Exact steps for others to reproduce the error
In edit mode, if I try to move the concerned geometry blender crashes systematically.

Thanks for the report. Can confirm the crash (but does not occur more frequently)
I've not debug this myself yet (Will do this later today if nobody get to this report)
But I think invalid material index value could also be handled to avoid crash
Forwarding this report to developers so they could decide if this is a valid bug or not
