Why does my datastorage pause the script?

for some reason, on the first pcall, the script doesn't run after it because it doesn't print hi. Why is it like this?

game.Players.PlayerRemoving:Connect(function(player)
	--[1] = coins
	--[2] = Best Time
	--[3] = Worst Time
	local leaderstats = {}

	table.insert(leaderstats,#leaderstats+1,player.leaderstats.Coins.Value)
	table.insert(leaderstats,#leaderstats+1,player.leaderstats["Best Time"].Value)
	table.insert(leaderstats,#leaderstats+1,player.leaderstats["Worst Time"].Value)

	local success, errormessage = pcall(function()
		DataStore:SetAsync(player.UserId,leaderstats)
	end)
	print("Hi")
	if not success then
		warn(errormessage)
	end
	--halos
	local tools = {}
	for _, halos in ipairs(game.ServerStorage.HaloInventory[player.Name]:GetChildren()) do
		table.insert(tools,#tools + 1,halos)
		print(halos)
	end

	local success4, errormessage4 = pcall(function()
		HaloStore:SetAsync(player.UserId, tools)
	end)

	if success4 then
		game.ServerStorage.HaloInventory[player.Name]:Destroy()
		game.ReplicatedStorage.HaloInventory[player.Name]:Destroy()
	else
		warn(errormessage4)
	end
end)
