Steps to Reproduce:

   private static int sequential = 0;
   private void requestFakePlayer(PlayerInteractEvent.RightClickItem event) {
       if (event.getEntity() instanceof ServerPlayer player && player.level() instanceof ServerLevel level) {
           // This one does NOT leaked because when you have
           // the same UUID as player you grab the same advancement
           // so this FakePlayer is not added to Criteria Triggers listeners
           if (event.getItemStack().getItem() == Items.STONE) {
               var fakePlayer = FakePlayerFactory.get(level, player.getGameProfile());
               reportFakePlayerCreated(player, fakePlayer);
           }
           // This one leaks, fails the uuid check and generate new PlayerAdvancements
           // triggering Criteria listeners
           if (event.getItemStack().getItem() == Items.STICK) {
               var gameProfile = new GameProfile(UUID.randomUUID(), "FakePlayer" + sequential++);
               var fakePlayer = FakePlayerFactory.get(level, gameProfile);
               reportFakePlayerCreated(player, fakePlayer);
           }
           // This also leaks, fails the uuid check and generate new PlayerAdvancements
          // triggering Criteria listeners
           if (event.getItemStack().getItem() == Items.ACACIA_BUTTON) {
               var fakePlayer = FakePlayerFactory.getMinecraft(level);
               reportFakePlayerCreated(player, fakePlayer);
           }
       }
   }

   private static void reportFakePlayerCreated(ServerPlayer player, FakePlayer fakePlayer) {
       player.sendSystemMessage(Component.translatable("FakePlayer %s created with profile: %s", fakePlayer.getDisplayName(), fakePlayer.getGameProfile().toString()));
   }

1. Code for reference
2. Grab one of the 3 items (stone, stick, acacia button) to test
3. Use it
4. Leave world, come back, check objects

Comments in code
I have seen a lot of modders do not use same UUID as the player, and from what I tested, if you fakePlayer.getAdvancements().stopListening() it bandaid fixes this issue.
