Datastore not working, for the third time?

Btw, before you flag this, im not spamming. I just need help. So i rewrote the script and added bind to close. And it prints saved successfully, but when i rejoin on studio, it doesn't load up. I've tried everything, Allowing studio to get API Access, making it public.... Adding bind to close.. NOTHING works... As far as i can tell, nothing is wrong with the script... Here is the script:

local datastoreservicee = game:GetService("DataStoreService") --- Gets Datastore Service
local AbiltiyStore = datastoreservicee:GetDataStore("AbilityStore") --Get's Ability Store


game.Players.PlayerAdded:Connect(function(player) -- Defining the player added
    local leaderstats = Instance.new("Folder") -- Creates A folder
    leaderstats.Name = "leaderstats" --- Names folder 'leaderstats'
    leaderstats.Parent = player -- parents folder to player --

    local Ability = Instance.new("StringValue") --- Makes a new string value which can store numbers and letters
    Ability.Name = "Ability" --- changes string value name to Ability
    Ability.Parent = leaderstats -- Puts it in the folder leaderstats

    local playeruserid = "Player_"..player.UserId -- Makes A playeruser id variable


    local data -- Defining the variable, will store something in it later

    local success, errormessage = pcall(function() --Uses this to search for errors during data saving
        data = AbiltiyStore:GetAsync(playeruserid) 
    end)
    if success then
        Ability.Value = data[1]
        print("Set Data Successfully")
    end
end)

--New function, when player leaves...
game.Players.PlayerRemoving:Connect(function(player) -- When player leaves...
    local Playeruserid = "Player_"..player.UserId -- Redifining the variable, because the variable before was local
     local data = {player.leaderstats.Ability.Value} -- Creates a table, so we can store numerous stuff in it

    local success, errormessage = pcall(function() -- Redifining again, as last time it was local, so withing that function only
        AbiltiyStore:SetAsync(Playeruserid, data)



    end)
    if success then -- Checking if the saving of data was a success (bool, so true or false)
            print("Data Saved Successfully")
        else -- If check returns false or nil then
            print("The was an error when saving the data")
            warn(errormessage)
        end

end)
game:BindToClose(function()
    local RunService = game:GetService("RunService")
    -- if the current session is studio, do nothing
    if RunService:IsStudio() then
        return
    end

    print("saving player data")

    -- go through all players, saving their data
    local players = game.Players:GetPlayers()
    for _, player in pairs(players) do
        local userId = player.UserId
        local data = AbiltiyStore[player.UserId]
        if data then
            -- wrap in pcall to handle any errors
            local success, result = pcall(function()
                -- SetAsync yields so will stall shutdown
                AbiltiyStore:SetAsync(userId, data)
            end)
            if not success then
                warn(result)
            end    
        end
    end

    print("completed saving player data")

end)
