Help with datastores

hi, I’m creating a core script server that manages a module that I created just for saving data. is a module that temporarily saves data within a table until the player exits or the server closes. This is the form

local DataStoreService = game:GetService("DataStoreService")
local DataStore = DataStoreService:GetDataStore("MASTERDATA")
local RunService = game:GetService("RunService")

local serverData = {}
------define globals -------------------------
--TODO output notificator and debugger
--------------------------------------------
------ SAVE DATA ---------------------------
serverData.SaveData= {
	prototype = {
		number = 0
	},
	metatable = {} --TODO da modificare la table 
}
serverData.SaveData.metatable.__index = serverData.SaveData.prototype
setmetatable(serverData.SaveData , {
	__call = function(plr)
		local newData = {}
		setmetatable(newData,serverData.SaveData.metatable)
		return newData 
	end
})
function serverData.SaveData:Update(plr,data)
	local oldData = {}
	setmetatable(oldData,serverData.SaveData.metatable)
	return oldData 
end
---------------------------------------------
------ GAME DATA ---------------------------
serverData.GameData= {
	prototype = {},
	metatable = {} --TODO da modificare la table 
}
serverData.GameData.metatable.__index = serverData.GameData.prototype
setmetatable(serverData.GameData , {
	__call = function(plr)
		local newData = {}
		setmetatable(newData,serverData.GameData.metatable)
		return newData 
	end
})
--------------------------------------------------------------------------------
serverData.sData = {}
serverData.gData = {}
function serverData:assemble(parent,serverRef)
	for i,v in pairs(parent:GetDescendants()) do
		if v == serverRef and v.ClassName == "ModuleScript" then
			serverData[v.Name] = require(v)
		end
	end
end
function serverData:newPlrData(plr)
	local key 
	local success, err = pcall(function()
		key = DataStore:GetAsync(plr.UserId)
	end)
	if success  then 
		if key then
			self.sData[plr.Name] = self.SaveData:Update(plr,key)
		else
			self.sData[plr.Name] = self.SaveData(plr)
		end
		self.gData[plr.Name] = self.GameData(plr)
	else
		if RunService:IsStudio() then 
			self.sData[plr.Name] = self.SaveData(plr)
			self.gData[plr.Name] = self.GameData(plr)
		else
			plr:Kick("Errore nel caricamente del DataStore dal server / Error loading Datastore from server")
		end
	end
	if plr then
		return self.sData[plr.Name] , self.gData[plr.Name]
	end
end
function serverData:removePlrData(plr)
	local sData , gData = self.sData[plr.Name],self.gData[plr.Name]
	if sData and gData then
		local success , error = pcall(function()
			print(self.sData)
			print(sData)
			local success, err = pcall(function()
				DataStore:SetAsync(plr.UserId,sData )
			end)
			if not success then
				warn(error)
			end
		end)
	end
	self.sData[plr.Name] = nil
	self.gData[plr.Name] = nil 
end
return serverData

The require of this and its methods are managed entirely by the Core server script in this way:

function main()
	Server:assemble(ServerScriptService,ServerInstance)
	game:BindToClose(function()
		for i_ , player in pairs(Players:GetPlayers())do
			local CloseBindThread = coroutine.wrap(function()
				Server:removePlrData(player)
			end)()
		end
	end)
end
Players.PlayerRemoving:Connect(function(player)
	Server:removePlrData(player)
	--some code ...
end)
----------------------------------------------
Players.PlayerAdded:Connect(function(player)
	--some code ...
	local sData , gData = Server:newPlrData(player)
	Server.sData[player.Name].number += 5 
	print(sData.number)
end)
------------------------------------------------
main()

On roblox studio don’t go datastores so I did publish to try it but the data is not saved. thank you in advance
