I've been dealing with the same crash. I *think* it's related to read/write permissions for the save folder. Try double-checking that the folder you're saving to ( documents/MyGames/Skyrim/saves or ModOrganizer/Profiles/(profile name) ) isn't marked read-only. Right-click, go to properties, and the read-only checkbox should be on the General tab. It's helped for me (so far) and I hope it helps you. Edit to add: Oops, Feb 20 *2016*, not Feb 20 2017. Well, I'll leave this up for the next person Googling.

Hooray for TerrorFox! Has done an awesome job on r/SkyrimMods, will do an awesome job here!
