The bug

In 1.19.2 and earlier, an error in a model file results in the pink-and-black cube missing model. In 22w42a, the entire pack instead fails to load, and you get the "resource reload failed" that removes all packs.

How to reproduce

• Download and equip the attached resource pack
• Get a diamond
  In 1.19.2, the diamond has the missing model
  In 22w42a, the pack cannot be equipped
