Camera is on humanoid,but locked, only see's one direction, Moves when character moves. Why?

Sorry for my English if it's bad.

this scripts doesnt seem to be working thats why the camera is locked.

Local Script on StarterCharacterScripts

local target = workspace.camera
local buttonfix = game.StarterGui.ScreenGui.mainmenu.TextButton
local camera = workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable
camera.CameraSubject = target
local angle = 0

while wait() do
    camera.CoordinateFrame = CFrame.new(target.Position)  --Start at the position of the part
                           * CFrame.new(0, 10, 0)       --Move the camera backwards 5 units
    angle = angle + math.rad(1)
end

Local Script in StarterGui.ScreenGUI.Frame

black = script.Parent.Parent
title = script.Parent
joingame = script.Parent.Parent.TextButton
whitestripe = script.Parent.Parent.Frame
cam = workspace.CurrentCamera


    for i = 0,1,0.1 do
    black.BackgroundTransparency = i
    wait(0.1)
end
    if black.BackgroundTransparency == 1 then
    script.Parent:TweenPosition (UDim2.new(0.5, -100, 0.1, -25), "Out", "Quad", 1, true)
    joingame.Visible = true 
    whitestripe.Visible = true
end

function onClicked()
title.Visible = false
joingame.Visible = false
whitestripe.Visible = false
    for i = 1,0,-0.01 do
        black.BackgroundTransparency = i
        wait (0.01)
    end
game.Workspace.CurrentCamera.CameraSubject = game.Players.LocalPlayer.Character.Humanoid
game.Workspace.CurrentCamera.CameraType = "Custom"

    wait(1)
    for i = 0,1,0.1 do
        black.BackgroundTransparency = i
        wait(0.1)
    end
end

script.Parent.Parent.TextButton.MouseButton1Down:connect(onClicked)

Thank you
