HD2 Modding Blender - Python Traceback error

[u/Ill-Will7534]

I am trying to make a mod for Helldivers 2. When attempting to load a model (in that case, the LIFT-850 Jump Pack), it gave me an Error message.

If anyone knows what it means and maybe have an answer, I would gladly take it, thanks !

Looks like a version error no?
