I was having this issue last night, where it would crash the instant the editor loaded. It turned out my laptop was trying to run it through the integrated Intel HD graphics chip (64mb), rather than through the NVidia GeForce card(4gb)… my laptop should automatically decide which one to use, but I had to force it to use my GeForce card for it to work.
It won’t be the case for everybody, but it’s worth a look for people having issues launching the editor.
