Camera does not return to player after being set to move slightly with cursor for main menu?

So I have this local script that makes the camera move slightly with the cursor on the main menu of my game, but when I click the play button on my main menu the camera does not return to the player and to default gameplay like it's supposed to, and instead stays stuck at the same position. Does anyone know how I can fix this so that when the play button is clicked the camera goes back to normal on the player and the camera no longer moves slightly with the cursor?

Local Script for camera on main menu:

local cam = workspace.CurrentCamera
local camPart = workspace["CameraPart"]
local mouse = game:GetService("Players").LocalPlayer:GetMouse()

repeat
	wait()
	cam.CameraType = Enum.CameraType.Scriptable
until cam.CameraType == Enum.CameraType.Scriptable

local maxTilt = 10

game:GetService("RunService").RenderStepped:Connect(function()
	cam.CFrame = camPart.CFrame * CFrame.Angles(
		math.rad((((mouse.Y - mouse.ViewSizeY / 2) / mouse.ViewSizeY)) * -maxTilt),
		math.rad((((mouse.X - mouse.ViewSizeX / 2) / mouse.ViewSizeX)) * -maxTilt),
		0
	)
end)

Local Script Play Button Clicked:

playbtn.MouseButton1Click:Connect(function()
	repeat wait()
		camera.CameraType = Enum.CameraType.Custom
	until camera.CameraType == Enum.CameraType.Custom
end)
