Having trouble with itempickup

Okay so I'm trying to make it so that the player can't pickup a certain item for 5 seconds here's what I have:

Code:

 
        private ItemStack deadt;
       
        @EventHandler
        private void Death(PlayerDeathEvent event){
           Player dead = event.getEntity();
            World world = dead.getWorld();
            Location location = dead.getLocation();
            deadt = new ItemStack(Material.NAME_TAG);
            world.dropItem(location, deadt);
            ((Item) deadt).setPickupDelay(100);
           
        }

This doesn't work the player can pick it up instantly.

 

Save player's name to list on death and start a delayed task to remove the entry 5 seconds later. On pickup event check if player's name is in that list and cancel the event if so. Simple.
