Datastore's SetAsync not working?

The SetAsync in question here is on line 49, the print statement above it fires but the one below does not. I've been cracking away at this for hours, recruiting the help of people on Discord to no avail. If anyone could assist me with this I would be greatly indebted to you.

local Data = game:GetService("DataStoreService"):GetDataStore("Data")

game.Players.PlayerAdded:Connect(function(Player)
    print("Key " .. Player.UserId)
    createCanSave(Player)
    local Success, Result = pcall(getPlayerData, Player)
    if Success then
        print(Result)
        print(Result.Stats.Exp)
        if Result and Result.Stats.Level > 0 then
            print("Got Result")
            setStats(Player, Result.Stats)
            setBackpack(Player, Result.Backpack)
        else
            print("Didnt get Result")
            defaultStats(Player)
            game.ReplicatedStorage.Weapons.StarterSword:Clone().Parent = Player:WaitForChild("Backpack")
        end
    else
        print("Error: " .. Result)
    end
end)

game.Players.PlayerRemoving:Connect(function(Player)
    print("Key " .. Player.UserId)
    if Player.CanSave.Value then
        print(Player.Name .. " is saving")
        local DataDictionary = {
            Stats = getStats(Player),
            Backpack = getBackpack(Player)
        }
        local Success, Result = pcall(setPlayerData, Player, DataDictionary)
        if Success then
            print("Successfully saved " .. Player.Name)
        else
            print("Error while saving " .. Player.Name .. " Message: " .. Result)
        end
    else
        print(Player.Name .. " can't save")
    end
end)
