Table DataStore NOT Working? help please. I made a DataStore Table and its not working

so i made a table datastore that if you touch a certain part it will put ur userid in the table and when u rejoin u will have "0" level and i tried everything and still does not work i tired reasearching and debugging myself but no changes anyways here is the code:

local ds = game:GetService("DataStoreService"):GetDataStore("IdkData")
local save = {}

game.Workspace.Crown.Touched:Connect(function(hit)
	if game.Players:GetPlayerFromCharacter(hit.Parent) then
		local Mainplayer = game.Players:GetPlayerFromCharacter(hit.Parent)
		table.insert(save, Mainplayer.UserId)
			print("userid saved!")
	end
end)

game.Players.PlayerAdded:Connect(function(player)
	local stats = ds:GetAsync(player.UserId.."Crown")
	
	print("hm")
	for i, v in pairs(save) do
		print("Bruh")
		if player.UserId == v then
			print("giving coins no werk")
			player.leaderstats.Level.Value = 0
		end
	end
end)

function saveData(player)
	
	local sucess, errorMessage = pcall(function()
		ds:SetAsync(player.UserId.."Crown", save)
	end)
	
	if sucess then
		print("Player Named "..player.Name.." Crown Has Been Saved!")
	else
		warn("Player Named ".. player.Name.." Had A Data Error!")
	end
end

game.Players.PlayerRemoving:Connect(function(player)
	saveData(player)
end)

game:BindToClose(function()
	for i, player in pairs(game.Players:GetPlayers()) do
		saveData(player)
	end
end)

Thanks!
