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)
