( since the first issue is closed i thought you wouldn't be able to see it so i'm putting it back here )
The crash i sent you is caused by an armor stand but the problem is that the armor stand won't render because the multi armor helmet is on it .
I crafted the multi armor and everything was fine as long as it wasn't on me or on the armor stand , thats why i said the " multi armor model" .

Here is an other crash from when it was on my character :
