Components of an EA Object

Hello There! I am currently new at CC and creating. I am trying to learn how to make my own CC, but I've seemed to have ran into a issue in S4S. I am getting error codes when trying to batch import on EA items in S4S and trying to create a new Mesh batch import. Can someone please help? I also did make sure I have all the requirements and updates for S4S before asking for help.

Error Code (when trying to import new mesh) The Sims 4 Studio - Version 3.2.0.6
System.NullReferenceException: Object reference not set to an instance of an object.
