item models broken

Sindce 25w45a my item models are broken. I used the custom_name component files in assets/minecraft/items/… All my textures are in the items folder and the model does work when I replace a normal item model. I use a multi-version pack and my models are in workshop/models/item/…

Steps to reproduce:

• Enable the pack

• Rename any sword to something like “Dark Saber“.

That is suppost to work and worked on previous snapshots/versions but since 25w25a it does not. It still doesn't in 25w46a.
