Opening any blueprint causes crash

I can play the level, opening the mesh editor menus, and do everything else that you can think of in Unreal. But when I open any and all blueprints it tries to load and then crashes every time. I had this problem before (link below) but deleting the Intermediate and Saved folders didn’t fix it this time. Opening any blueprint crashes ue4 - Programming & Scripting - Unreal Engine Forums

Any help would be greatly appreciated.
