My camera doesnt go back to the player when being set to "custom"?

Hi there, i have this game that has a menu when you spawn in, in this menu the camera is changed to a different area and once you press play it should go back to the player. Ive even done this task many times before but for some reason the camera isnt going back to normal

below shows the important stuff you need to know in the script

--//Player Var
local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local cam = workspace.CurrentCamera

--//Service Var
local rep = game:GetService("ReplicatedStorage")
local ts = game:GetService("TweenService")

--//Gui Var
local gui = script.Parent
local blackScreen = gui.BlackScreen
local logo = gui.Frame.Logo
local logoText = gui.Frame.Logo
local menu = false
local running = false

--//Other
local camPart = workspace.CamPart1
local camPos1 = workspace.CamPos1
local camPos2 = workspace.CamPos2

player.CharacterAdded:Connect(function()
    menu = true
    cam.CameraType = Enum.CameraType.Scriptable
    cam.CFrame = camPart.CFrame
    rep.Music.Menu:Stop()
    rep.Music.Menu:Play()
    wait(3)
    for i = 1,100 do
        wait()
        blackScreen.BackgroundTransparency = blackScreen.BackgroundTransparency + 0.01
    end
end)

gui.Frame.PlayButton.MouseButton1Click:Connect(function()
    --camTween1:Cancel()
    menu = false
    cam.CameraType = Enum.CameraType.Custom
end)
