When you’re looping through the items inside “playerBackpack” on line 17, there are not any items inside this folder. Since this does not appear to be in use, it is not necessary to have it.

When you’re saving the data, you save it as a table containing all the tool names, so you can simply load these items from the table. You should also use pcall() when saving data to catch errors when saving. The example below will save and load the tools when a player leaves/joins.

local DataStoreService = game:GetService("DataStoreService")
local toolsData = DataStoreService:GetDataStore("ToolsData")

---> load data when player joins
game.Players.PlayerAdded:Connect(function(player)
	local data
	local success, erromsg = pcall(function()
		data = toolsData:GetAsync(player.UserId)
	end)

	if success then
		if data then
			for i,tool in pairs(data) do
				-- Since you're saving the tool names to the table, you can search for them in a certain place.
				local toolClone = game.ServerStorage[tool]:Clone()-- Change to where you are storing the tools in the game.
				toolClone.Parent = player.Backpack
			end
		end
	end
end)

---> save data when player leaves
game.Players.PlayerRemoving:Connect(function(player)
	local Tools = {}
	for i,tool in pairs(player.Backpack:GetChildren()) do
		if tool:IsA("Tool") then
			table.insert(Tools,tool.Name)
		end
	end

	local success, errormsg = pcall(function()
		toolsData:SetAsync(player.UserId,Tools)
	end)

	if not success then
		warn("Failed to save tools data - "..errormsg)
	end
end)

game.Players.PlayerAdded:Connect(function(player) – load data
local data
local success, erromsg = pcall(function()
data = toolsData:GetAsync(player.UserId)
end)

if success then
	if data then
		for i,tool in pairs(data) do
			local toolClone = game:GetService("ServerStorage").Tools:FindFirstChild(tool):Clone()
			toolClone.Parent = player.Backpack
		end
	end
end

end)

i tried this but it didnt work still

I tested the script I sent above in my game and it is working. Are there any errors in your output when trying to load/save data?
