Either have a world-wide list of recipe that can be available to the auto crafter or registering who is interacting with it (even better, make people "sign" inside the block so they can add their recipes or remove them at will)
But as it is now, crafter can be a problem for some maps/datapacks.
This has the potential to break many maps, datapacks, and mc experiences.
One solution could be:
When placing the crafter the block saves the player's UUID to the block's nbt.
Block checks if the recipe is unlocked for the player matching the UUID.
If successful, the block crafts and spits out the items.
