How do I disable the crafting grid in the inventory?

[ezspi]

In my game, I'm trying to make it so you can't rearrange your inventory, let alone craft stuff. I have already disabled the "Player Click Slot" event, but items can still be moved into the grid with hotkeys. Is this a bug or can it be stopped?

How do I disable the 2x2 crafting?

So I've seen some games where if you try to use the vanilla 2x2 crafting in your inventory, it closes your inventory so you can't vanilla craft to make vanilla items. I've heard it is hard to explain, but if anyone knows how to, can you tell me? It could be easier to type it out. Thank you
