The very same happened to me...
For some reason, the TGA files were not exporting properly to the folders (including the armor folders), and when I cooked the mod without the TGA files, I got that very same result as you:
So pretty much what I had to do was uncook all the game files AGAIN :wallbash: this time using the -skiperrors extension at the end. TGA files got extracted properly and I was finally able to re-import it.
Hope it helps!
