Tools datastore not saving upon PlayerRemoving?

Hello, so I've been trying to save upon playerremoving but it never wants to work. I even used BindToClose() and I know it works 30 seconds before shutdown they said. But when I leave, the tool wont save.

This is currently my code right now:

local dataStoreService = game:GetService("DataStoreService")
local dataStore = dataStoreService:GetDataStore("BackpackSave")
game.Players.PlayerAdded:Connect(function(player)
	pcall(function()
		local tool = dataStore:GetAsync("User-"..player.UserId)
		if tool then
			for i,v in pairs(tool) do
				local toolFound = game.ReplicatedStorage.Items:FindFirstChild(v)
				if toolFound  then
					toolFound:Clone().Parent = player.Backpack
				end
			end
		end
	end)
end)

game.Players.PlayerRemoving:Connect(function(player)
	pcall(function()
	local toolsSave = {}
	
		for i, tool in pairs (player.Backpack:GetChildren()) do
			if tool then
				table.insert(toolsSave,tool.Name)
			end
		end
		dataStore:SetAsync("User-"..player.UserId,toolsSave)
end)
end)

game:BindToClose(function()
	

	for _, player in pairs(game.Players:GetPlayers()) do -- notice that you can loop through every player left in the server so the function can run for them
		local toolsSave = {}
		for i, tool in pairs (player.Backpack:GetChildren()) do
			if tool then
				table.insert(toolsSave,tool.Name)
			end
		end
		dataStore:SetAsync("User-"..player.UserId,toolsSave)
	end
end)

Any help is appreciated...

It worked fine for me. Are you sure you have API Services enabled? (Game Settings -> Security -> Enable Studio Access to API Services)? Make sure to restart your studio after you save.
