Crashes when exporting .smd

[Tandori]

After the Face and Top of my model export Blender will crash/become unresponsive. Blender is still using my cpu so I don't know whether to leave it for hours or if there's a real issue I need to fix. I have done this process before with a different model and exporting didn't take nearly as long, though that was lower polycount and on an older version of Blender.

Here is a screenshot with details before I begin the exporting process: https://imgur.com/a/d1tWpcX


Edit: I let it run overnight and it is still not responding.
