I can get it open. load parent esm, but as of yesterday, I have a glitch where all character torsos are invisible whether they wear armor, clothes or nothing. Still not sure if it's something I did or a problem on Bethesda's side. CK has also been very unstable since that update. I must have crashed ten times in two hours.
There is a new bug, where edited races and armors has invisible slots. Also, in the case of armors, the same piece of armors can be equipped without counting for the one piece limit and didn't give protection. To have this glitch, you only need to open a previously working file (where a race or armor has been edited) and save (even if you changed nothing).
