Error on specific card

[S00pergang]

• Koikatsu Sunshine ver : 1.4.1
• HF Patch ver : 1.16
• Blender ver : 3.6.9
• KKBP_Exporter ver : 4.30
• KK Blender Porter ver : 6.6.2
• MMD Tools ver : 2.9.2

I'd like to post the card causing it, but I'm anxious of having cards stolen. So if I can DM you it later somehow somewhere that'd be great

actually, after running more tests, I believe it has to do with these following accessories

BTW it seems when I successfully import (using the default chara I exported) The hair, clothes and body are messed up, body is invisible, hair is white with a yellow gradient and clothes are also blank.
