Please help with datastores

Hello, I am trying to make saving stages for my obby. But I have spent hours on it and it hasn’t worked… (sorry for bad explanation, I haven’t for a bit so I’m kinda dizzy.)
Here is my script:

local players = game:GetService("Players")
local dataStoreService = game:GetService("DataStoreService")

local database = dataStoreService:GetDataStore("Stages")
local sessionData = {}

function PlayerAdded(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	
	local stage = Instance.new("IntValue")
	stage.Parent = leaderstats
	stage.Name = "Stage"
	
	local success = nil
	local playerData = nil
	local attempt = 1
	
	repeat
		success, playerData = pcall(function()
			return database:GetAsync(player.UserId)
		end)

		attempt += 1
		if not success then
			warn(playerData)
			task.wait(3)
		end
	until success or attempt == 5
	
	if success then
		print("Connected to database")
		if not playerData then
			print("Assigning default data")
			
			playerData = {
				["Stage"] = 1
			}
		end
		sessionData[player.UserId] = playerData
	else
		warn("Unable to get data for", player.UserId)
		player:Kick("Unable to load your data! Please try again later.")
	end
	
	stage.Value = sessionData[player.UserId].Stage
	stage.Changed:Connect(function()
		sessionData[player.UserId].Stage = stage.Value
	end)
	
	leaderstats.Parent = player
end
players.PlayerAdded:Connect(PlayerAdded)


function PlayerLeaving(player)
	if sessionData[player.UserId] then
		print("test")
		local success = nil
		local errorMsg = nil
		local attempt = 1
		
		repeat
			success, errorMsg = pcall(function()
				database:SetAsync(player.UserId, sessionData[player.UserId])
			end)
			
			attempt += 1
			if not success then
				warn(errorMsg)
				task.wait(3)
			end
		until success or attempt == 5
		
		if success then
			print("Data saved for", player.Name)
		else
			warn("Unable to save for", player.Name)
		end
	end
end
players.PlayerRemoving:Connect(PlayerLeaving)

Never mind, I found out that this script DOES work but when I test it in studio, I have to kick my player to save it
