How do i set the camera to be above the head facing down when my character touches a part?

My friend and I have made a dungeon and before the latest ROBLOX update when you touched the entrance your camera would face downwards and be above your head. Now ROBLOX has updated and the script only functions when its an active script as soon as the player joins the game

it also only works as a localscript

This is the script:

local offset = Vector3.new(-2.5,15,0)
local fieldOfView = 80
local player = game.Players.LocalPlayer
local camera = game.Workspace.CurrentCamera
local RunService = game:GetService("RunService")

--player.DevCameraOcclusionMode = Enum.DevCameraOcclusionMode.Invisicam

camera.FieldOfView = fieldOfView
camera.CameraType = "Scriptable"
 function onRenderStep()
 local playerPosition = player.Character.HumanoidRootPart.Position
 local cameraPosition = playerPosition + offset
 camera.CoordinateFrame = CFrame.new(cameraPosition, playerPosition)
end

please help

thank you
