Player can't move when changing camera?

When I change the camera to scriptable and set the view to look at the players head. The Player can no longer walk.

wait()

local Offset = 10

local Cam = Game.Workspace.CurrentCamera
local Char = Game.Players.LocalPlayer.Character
Cam.CameraType = "Scriptable"

Game:GetService("RunService").RenderStepped:connect(function()
    Cam.CoordinateFrame = CFrame.new(Char.Head.Position + Vector3.new(0,Offset,0),(Char.Head.Position))
end)
