Paragon assets may have introduced some bugs with the engine

Ever since I downloaded some of the free Paragon assets, Unreal Engine crashes randomly on projects that I’ve added them too, even if they aren’t in the map. Even placing certain ones in the map causes it to crash. I also set up a blank project, only gave it one of the few that worked properly, and I can’t package it because the Output log tells me the file n@me is too long.
