I'm experiencing the same. Tried all of the suggested fixes too. 50/50 isn't reliable, as a piece of cc can load fine once and then not the next time.
Repair install only helps partly and resets once you exit EA or restart your computer. Resourceconfig file was not the issue.
Tried a clean install too, and it only proved it wasn't a mod issue. I had no mods in place, and cc would still randomly crash things or not load the game. Someone suggested downgrading to dx9 in the game options, but this didn't work either.
This is an issue on EAs end, not the modders or cc creators.
