It's not working for me too for some reason.

Not working for me for some reason. I did it the same as the other datapacks I have

Nice stuff! I see that this is a small and simple datapack, but if I may make a suggestion, I notice that you're using nbt in your tick function, not once, not 6 times, but twice for every player and an extra 4 times for every entity. I've only looked at the tick function so far, but nbt is very very slow, especially done every tick and combined with @e.

If you ever need to optimize this pack, I would recommend using a predicate to read the player's selected item, and maybe only check the other things if the player throws an item on the ground. You could set up a hidden advancement that triggers a function when the player's inventory changes, then immediately look for any new, dropped items. If it finds one, then you read the nbt. If that nbt matches the nbt you're searching for, give it a /tag. It's WAY faster to use the tag= selector than it is to use nbt= because any time you read or write nbt to or from an entity, the game has to do some disgustingly slow serialization, so you want to minimize it as much as possible.

If you're not worried about datapack execution speed, ignore all this. If you are worried, hmu I've been fixing a lot of my own mistakes recently
