CAS issue

I have tried everything, from removing all of my CC to creating a new Sims 3 folder in my documents and I still have this error. I am pulling my hair out trying to find out what is causing it and was wondering if any of you knew. Any help would be greatly appreciated.

 

do you have any package files with cas related content in it? because to me, it seems like it's a corrupted file with a bad mesh in it

It could be that, but since I have already run it without CC and still got the same issue I don't think it is. I'm still trying to figure it out. My sims are totally normal in game but when I open them in CAS they all look like that.

but if you have .package files you have to manually move them out of the folder because the launcher doesn't see those as custom content.

yeah that's what I mean, I removed my entire mods folder plus the whole run with no CC to no avail. I have run it 2 times when I created a new Sims 3 folder and got results but now I'm trying to pinpoint the problem.
