When i make camera manipulation why can't i move?

It won't let me move when it's like this.

Here's the script

local Player = game.Players.LocalPlayer
local cam = workspace.CurrentCamera

Player.CharacterAdded:Wait()
Player.Character:WaitForChild("Humanoid")

cam.CameraSubject = Player.Character.Head
cam.CameraType = Enum.CameraType.Attach
cam.FieldOfView = 60

game:GetService("RunService").Stepped:Connect(function()
    cam.CFrame = CFrame.new(Player.Character.HumanoidRootPart.Position) * CFrame.new(0, 12, 0) * CFrame.Angles(math.rad(270), 0, 0)
end)
