Can't export specific mesh

So I'm currently making a scene in blender using sims 4 assets. At the moment, I'm trying to export a corbel, but each one I try to export gets an error like the one below. This doesn't seem to happen for any other mesh I export, and it's only the mesh I have trouble exporting. Anything I can do to fix it?

Sims 4 Studio 1.3.3.6 (Apple Blossom)
