Datastore won't load data?

Code below won't load data, no errors, I have no idea what's going on.

local dataStoreService = game:GetService("DataStoreService")
local cubeDataStore = dataStoreService:GetDataStore("Cubes")

game.Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder",player)
	leaderstats.Name = "leaderstats"

	local cubesmade = Instance.new("IntValue",leaderstats)
	cubesmade.Name = "Cubes"
	cubesmade.Value = 0

	local playerUserId = "player_"..player.UserId
	local cubeData
	local success, errormessage = pcall(function()
		cubeData = cubeDataStore:GetAsync(playerUserId)
	end)

	if success then
		cubesmade.Value = cubeData
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local playerUserId = "player_"..player.UserId
	local cubeValue = player.leaderstats.Cubes.Value
	local success, errormessage = pcall(function()
		cubeDataStore:SetAsync(playerUserId, cubeValue)
	end)
end)

game:BindToClose(function()
	for _, player in pairs(game.Players:GetPlayers()) do
		local playerUserId = "player_"..player.UserId
		local cubeValue = player.leaderstats.Cubes.Value
		local success, errormessage = pcall(function()
		end)
		cubeDataStore:SetAsync(playerUserId, cubeValue)
	end
end)

Try this

local DSS = game:GetService("DataStoreService")

local DataStore = DSS:GetDataStore("CubicData")







game.Players.PlayerAdded:Connect(function(player)

	local leaderstats = Instance.new("Folder")

	leaderstats.Parent = player



	local Cubes = Instance.new("IntValue")

	Cubes.Name = "Cubes"

	Cubes.Parent = leaderstats



	local data

	local success, errorMessage = pcall(function()

		data = DataStore:GetAsync(player.UserId)

	end)

	if success and data ~= nil then

		print("Data successfully loaded!")

		Cubes.Value = data.Cubes

	else

		warn(errorMessage)

	end

end)



game.Players.PlayerRemoving:Connect(function(player)

	local leaderstats = player.leaderstats

	local data = {

		Cubes = leaderstats.Cubes.Value; 

	}

	local success, errorMessage = pcall(function()

		DataStore:SetAsync(player.UserId,data)

	end)

	if success then

		print("Data successfully saved!")

	else

		warn(errorMessage)

	end

end)

Hope this helps!!
