Well, that was short lived. After updating to 8.1 and having to reinstall Evernote it's crashing on every sync again. Boo.
I thought I had tried this already, but I just logged out of Evernote and then back in and it actually synchronized my data without crashing. (Was previously crashing every time it tried to sync.) I made some changes and sync'd back out and that seems to have worked as well. YMMV, but thought it might help.
