Daz Studio Crashes to export FBX Morphs

basabdas18

I have my character loaded with several outfits and props. The Fbx is around 450MB. I exported it many times and imported it to Unity, no issues. But exporting the same with 12 morphs selected, Daz Studio is crashing. I tried it many times, the same result. By the way, I just have updated Daz Studio to 4.20, I didn't try it older version, so I have no idea how to resolve it. Any help will be much appreciated.
