Uninstalled/reinstalled race mod. Now CTD on new game.

[VoidTerraFirma]

So I was using the succubus race mod from the Nexus. No problems with it. Worked fine. I wanted to replace the wings with the ones from the PSQ Transform Pack. Didn't turn out the way I'd hoped. Oh well, guess I'll just be happy with the race mod's original wings. So I uninstalled the Succubus race, then reinstalled it. Upon selecting new game, instant CTD. Huh? Whatever. I then uninstalled it again, and also removed the PSQ Transform Pack, figuring that having it on there was causing some kind of problem. Reinstalled the race mod. CTD on new game. Disabling the mod and starting a new game works fine. No crash. No problem. Activate the mod...fucking CTD. So I know this mod is the culprit, but can't figure out why.

Tried some different things, each time alongside uninstalling and reinstalling the race mod.
- Moved race mod around in load order. Started game with race mod active. CTD on new game.
- Ran LOOT. Started game with race mod active. CTD on new game.
- Ran FNIS (not sure why this would be necessary, but getting aggravated at this point). Started game with race mod active. CTD on new game.
- Deleted the race mod zip. Redownloaded from Nexus. Started game with race mod active. CTD on new game.
- Manually installed race mod instead of using MO. Started game with race mod active. CTD on new game.
- Uninstalled, then reinstalled the race mod's requirements. Started game with race mod active. CTD on new game.
- Punched my grandma in the head for looking at me funny. Started game with race mod active. CTD on new game.

Again, I should point out that I know the race mod is the culprit. Starting the game without it active and selecting New Game does not cause a crash or any other problem. And the race mod was working perfectly fine until I stupidly tried to change the wings. One would expect that uninstalling the changed mod and reinstalling it from scratch (as in, without the change I tried to make, directly from the zip file) would be of no consequence. What is this shit?

I'm using Mod Organizer, if that helps at all.
