DataStore Not Saving/Loading how to fix?

My DataStore script won't save or maybe won't load players data. I have a button in game that raises the values of GoldRubyC and CollectionValue

local datastore = game:GetService("DataStoreService"):GetDataStore("tablohazerjia1")


game.Players.PlayerAdded:connect(function(player)
        local PlayerProfile = Instance.new("Folder")
    PlayerProfile.Name = "PlayerProfile"
    PlayerProfile.Parent = player


    -------------------- [Collected Treasure Verified]-
    local TreasuresCollected = Instance.new("IntValue")
    TreasuresCollected.Name = "TreasuresCollected"
    TreasuresCollected.Parent = PlayerProfile
    ---------------------------------------------------


    ---------------------[Treasures]--------------------
    local GoldRubyC = Instance.new("IntValue")
    GoldRubyC.Name = "GoldRubyC"
    GoldRubyC.Parent = PlayerProfile.TreasuresCollected
    ---------------------------------------------------


    ---------------------[Collection Value]------------
    local CollectionValue = Instance.new("IntValue")
    CollectionValue.Name = "CollectionValue"
    CollectionValue.Parent = PlayerProfile
    --------------------------------------------------



    local key = "user_" .. player.userId

    local storeditems = datastore:GetAsync(key)

    if storeditems then
        TreasuresCollected.Value = storeditems[1]
        GoldRubyC.Value = storeditems[2]
        CollectionValue.Value = storeditems[3]
    else
        local items = {TreasuresCollected.Value, GoldRubyC.Value, CollectionValue.Value}
        datastore:SetAsync(key, items)
    end
end)

game.Players.PlayerRemoving:connect(function(player)
    local items = {player.PlayerProfile.TreasuresCollected.Value, player.PlayerProfile.TreasuresCollected.GoldRubyC.Value, player.PlayerProfile.CollectionValue.Value}
    local key = "user_" ..player.userId

    datastore:SetAsync(key, items)
end)
