Specifying a nonexistent tag in an item definition crashes the game

To Reproduce:

1. Create a resource pack with an item definition that replaces something vanilla - in my case, I used the Enchantment Book.

2. Using the component condition, check for something via a tag that doesn’t exist (note that creating the tag in a Datapack will actually prevent this from happening)

3. The game crashes upon entering a world.

4. Error: java.lang.UnsupportedOperationException: Tag TagKey[minecraft:enchantment / minecraft:doesnt_exist] can't be dereferenced during construction

Expected:

Either the resource pack wouldn’t load, the item definition wouldn’t load, or it would enter in a “safe mode“ similar to broken definitions in a Datapack.

I could see this being very dangerous, since friends could send packs that crash the game or servers who are configured to send a resource pack may purposefully or accidentally crash their players.
