Unreal Chaos Destruction

has anyone got this working? I downloaded the 4.23 and compiled it and attempted to re-create what the developers did at e3 to make the destructible chaos geometry asset from a static mesh but everytime i click on the newly created geometry chaos asset in the world and select the fracture feature(upper left hand corner kinda hidden) it crashes! this really isnt a bug report but rather investigating what ue4 build was working for peeps.
