Sorry if that was vague, but you assuredly have a mod issue, it's just not coming from ICV. I consolidated my mod list by swapping/removing/updating a few, so I can't pinpoint exactly what it was. Make sure you're not loading 3/4UC, that I do know. I've removed all custom civs for now as well.what exactly do you mean by cleaned through? I deleted cache mod userdata and verified game integrity on steam
If you've verified integrity and tried starting a game with bare-bones VP, only for it to still result in CTD, then I'd be stumped.
