Hello, I've recently switched hosts. Doing this, I had to update to 1.19.3. But, after all of this, most of IA's custom items have suddenly broken. I have tried redownloading IA, updating it, and deleting the folder for it. Here is an image:

This happens to anything with a custom model, and all of my custom packs.
Here is also my log:
