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...
