Why does the death counter work but the autosave does not?

So I wanted to make a death leaderboard with autosave for me game, so I made this script:(Someone else's script)

--This script was made by ROBLOXSCRIPT ISEASY
local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("Deaths") -- Change this with a random name.

game.Players.PlayerAdded:Connect(function(Player)
    local Leaderstats = Instance.new("Folder", Player)
    Leaderstats.Name = "leaderstats"
    local Currency = Instance.new("IntValue", Leaderstats)
    Currency.Name = "Deaths" -- Change this with your currency name.
    Currency.Value = 0

    local humanoid = char:FindFirstChild("Humanoid")

    humanoid.Died:Connect(function()

        Deaths.Value = Deaths.Value + 1

    local Data = DataStore:GetAsync(Player.UserId)
    if Data then
        Currency.Value = Data
    end
end)

game.Players.PlayerRemoving:Connect(function(Player)
    DataStore:SetAsync(Player.UserId, Player.leaderstats.Deaths.Value)
end)

The death counter works, but the autosave does not. Will you help me?
