Datastore breaking with no errors?

So I'm trying to save the player's stats and their parts in game. Alone the part saving works but when I added the stat saving it broke and didn't run the part saving.

local PartStoring = game:GetService("DataStoreService"):GetDataStore("BetaParts")
local StatStoring = game:GetService("DataStoreService"):GetDataStore("BetaStats")

--//Variables
local placingStorage = game.ServerStorage.PlaceableParts

--//Tables
local statHolder = {}

game.Players.PlayerRemoving:connect(function(player)
	if game.Workspace:FindFirstChild(player.Name.."'sItems") then
		
		print('hello is me fruim d a uder si de') --Prints
		
		local key = "user_"..player.userId
		
		--Stats Storing
		local Stats
		for k,l in pairs (statHolder) do
			if l[1] == player.Name and l[2] then
				Stats = l
			end
		end
		print('mid check') --Prints
		if Stats then
			StatStoring:SetAsync(key,Stats[2])
			table.remove(Stats)
		end
		--Part Storing
		print('saving parts') --Doesn't print
		
		local model = game.Workspace[player.Name.."'sItems"]
		local FinalString = {}
		
		for i,v in pairs (model:GetChildren()) do
			x,y,z,rx,ry,rz = v.PrimaryPart.CFrame.X, v.PrimaryPart.CFrame.Y, v.PrimaryPart.CFrame.Z, v.PrimaryPart.CFrame:toEulerAnglesXYZ()
		    local comp = {x,y,z,rx,ry,rz}
			local everything = {v.Name,comp}
			if model:FindFirstChild("Settings") then
				for k,l in pairs (model.Settings:GetChildren()) do
					table.insert(everything,10000,l.Name)
					table.insert(everything,10000,l.Value)
				end
			end
			table.insert(FinalString,everything)
		end
		
		if #FinalString >= 1 then
			print('saved') --of course doesn't print
			PartStoring:SetAsync(key, FinalString)
		end
	end
end)
