Game freezes when opening Build Mode - kids section

When I go into build mode, and i click on the kids section (like toys, or infants stuff etc), the game completely freezes and then closes. i removed cc etc, the problem is still there. even if i go on like 'all objects' from the build mode menu and i scroll down until i find the kids objects, it does the same thing: it freezes etc. doesnt happen with the other categories of objects (or at least not yet). what can i do? Thanks.
