Short description of error
Basically, I believe that it is the same error https://developer.blender.org/T79343 but to be honest, I'm not 100% sure.
What you need to do is somehow keep the object in edit mode, remove active state from it then export. If you export object from Edit mode error will not happen, I guess export script have some checking if object in edit mode and if it so, make some workarounds. But if you hide the object when it in Edit mode, it stays in Edit mode until you select it again.

So in the test file you can get this weird state:
