Data Store Script not working properly?

Greetings people, I've got a serious problem with data storing. It seems that, although the pcall says it was right, the player's data doesn't recover when he rejoins. Is there a reason why this happens?

local Players = game:GetService("Players")
local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("PlayerStat2019")
local MarketplaceService = game:GetService("MarketplaceService")

Players.PlayerAdded:Connect(function(Player)
	local Leaderboard = Instance.new("Folder",Player)
	Leaderboard.Name = "leaderstats"
	
	local Wins = Instance.new("IntValue",Leaderboard)
	Wins.Name = "Wins"
	Wins.Value = 0
	
	local Coins = Instance.new("IntValue",Player)
	Coins.Name = "Coins"
	Coins.Value = 0
	
	local XP = Instance.new("IntValue",Player)
	XP.Name = "XP"
	XP.Value = 0
	
	local Time = Instance.new("IntValue",Player)
	Time.Name = "Time"
	Time.Value = 0
	
	local Level = Instance.new("IntValue",Leaderboard)
	Level.Name = "Level"
	Level.Value = 1
	
	--// Tools
	local BoughtTools = Instance.new("Folder",Player)
	BoughtTools.Name = "BoughtTools"
	
	--//Chatting and Gamepasses
	
	local VIPGamepass = 7622135
	local MegaVIPGamepass = 7622108
	local BanHammerGamepass = 7622101
	
	local HasVIP
	local HasMegaVIP
	local HasBanHammer
	
	local Success,Error = pcall(function()
		HasVIP = MarketplaceService:UserOwnsGamePassAsync(Player.UserId,VIPGamepass)
		HasMegaVIP = MarketplaceService:UserOwnsGamePassAsync(Player.UserId,MegaVIPGamepass)
		HasBanHammer = MarketplaceService:UserOwnsGamePassAsync(Player.UserId,BanHammerGamepass)
	end)
	
	if Success and HasBanHammer == true then
		game.ServerStorage:WaitForChild("Tools").BanHammer:Clone().Parent = BoughtTools
	end
	
	if Success and HasMegaVIP == true then
		if Player.Backpack:FindFirstChild("Boombox") == nil and Player.Character:FindFirstChild("Boombox") == nil then
			game:GetService("ServerStorage"):WaitForChild("Tools").Boombox:Clone().Parent = Player.StarterGear
			game:GetService("ServerStorage"):WaitForChild("Tools").Boombox:Clone().Parent = Player.Backpack
		end
	end
	
	if Success and HasVIP == true then
		if Player.Backpack:FindFirstChild("Boombox") == nil and Player.Character:FindFirstChild("Boombox") == nil then
			game:GetService("ServerStorage"):WaitForChild("Tools").Boombox:Clone().Parent = Player.StarterGear
			game:GetService("ServerStorage"):WaitForChild("Tools").Boombox:Clone().Parent = Player.Backpack
		end
	end
	
	--// Data system
	local Key = "Key_"..Player.UserId
	local Data
	
	local Success,Error = pcall(function()
		Data = DataStore:GetAsync(Key)
	end)
	
	if Success then
		if Data ~= nil then
			Coins.Value = Data["Coins"]
			Wins.Value = Data["Wins"]
			XP.Value = Data["XP"]
			Level.Value = Data["Level"]
			print("Data of "..Player.Name.." successfully got!")
		elseif Data == nil then
			Data = {
				["Coins"] = Player.Coins.Value;
				["Wins"] = Player.leaderstats.Wins.Value;
				["XP"] = Player.XP.Value;
				["Level"] = Player.leaderstats.Level.Value;
				["BoughtTools"] = {};
			}
			DataStore:SetAsync(Key,Data)
			print("Data of "..Player.Name.." successfully got!")
		end
	else
		error("Couldn't get data from DataStore: "..Error)
	end
	
	--// Game related script
	Player.CharacterAdded:Connect(function(Character)
		Character.Humanoid.Died:Connect(function()
			if Character:FindFirstChild("GameTag") then
				Character:FindFirstChild("GameTag"):Destroy()
			end
			
			Player:LoadCharacter()
		end)
	end)
end)

Players.PlayerRemoving:Connect(function(Player)
	print("Debug")
	
	local Key = "Key_"..Player.UserId
	local Data = {
		["Coins"] = Player.Coins.Value;
		["Wins"] = Player.leaderstats.Wins.Value;
		["XP"] = Player.XP.Value;
		["Level"] = Player.leaderstats.Level.Value;
		["BoughtTools"] = Player:WaitForChild("BoughtTools"):GetChildren();
	}
	
	local Success,Error = pcall(function()
		DataStore:SetAsync(Key,Data)
	end)
	
	game:GetService("StarterGui"):SetCore("ChatMakeSystemMessage",{
		Text = "[SYSTEM]: "..Player.Name.." left the game!",
		Font = Enum.Font.SourceSans,
		Color = Color3.new(255, 0, 0),
		FontSize = Enum.FontSize.Size14
	})
	
	if Success then
		print("Data of "..Player.Name.." successfully saved!")
	else
		error("Couldn't save data to DataStore: "..Error)
	end
	
	local Character = Player.Character or Player.CharacterAdded:Wait()
	local Gametag = Character:FindFirstChild("GameTag")
	Gametag:Destroy()
end)

game:BindToClose(function()
	local PlayersLeft = Players:GetPlayers()
	
	for i = 1, #Players do
		local Player = Players[i]
		
		local Key = "Key_"..Player.UserId
		local Data = {
			["Coins"] = Player.Coins.Value;
			["Wins"] = Player.Wins.Value;
			["XP"] = Player.XP.Value;
			["Level"] = Player.leaderstats.Level.Value;
			["BoughtTools"] = Player:WaitForChild("BoughtTools"):GetChildren();
		}
		
		local Success,Error = pcall(function()
			DataStore:SetAsync(Key,Data)
		end)
		
		if Success then
			print("Data of "..Player.Name.." successfully saved!")
		else
			error("Couldn't save data to DataStore: "..Error)
		end
	end
end)

Problem solved.
