bump, crashing too, I 've solved half of issues by installing latest windows 10 build, but after installing that and I use -d3ddebug flag editor says that I don’t have dx11 feature level 10 
lol, !? I am sure I have
but its still crashing , crashing when trying to change materials in static mesh editor, sometimes crash if I am trying to change default values in blueprint. sometimes tottaly freezes , so I need to do hard reset.
hope it will be solved soon.
