Jittery camera on one game but not the other

Hello, im currently working on a custom camera for a test game but it seems jittery, on the first game that is the game im trying to fix the camera on, the second game is where the camera is completely fine. In both games, the scripts are exactly the same but is delayed in the test game??

the script

local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")
local RootPart,Head = Character:WaitForChild("HumanoidRootPart"),Character:WaitForChild("Head")

local Camera = workspace.CurrentCamera

-- [ Services ] --
local RunService = game:GetService("RunService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local UIS = game:GetService("UserInputService")

-- [ Modules ] --
local Tween = require(ReplicatedStorage.Modules.Tween)

-- [ Data ] --
local TweenPower = 1750
local CameraStiffness = script:GetAttribute("CameraStiffness")

local CanRun = not UIS.TouchEnabled

local CameraBlock = Instance.new("Part", Character)
CameraBlock.Size = Vector3.new(1, 1, 1)
CameraBlock.Name = "CameraBlock"
CameraBlock.CastShadow = false
CameraBlock.CanTouch = false
CameraBlock.CanCollide = false
CameraBlock.Transparency = 1
CameraBlock.Position = Character.PrimaryPart.Position

local BodyPosition = Instance.new("BodyPosition", CameraBlock)
BodyPosition.MaxForce = Vector3.new(math.huge, math.huge, math.huge)

-- [ Functions ] --
local function Loop()
	BodyPosition.P = TweenPower * CameraStiffness
	BodyPosition.Position = Head.CFrame.Position + Vector3.new(0, (Humanoid.HipHeight - script:GetAttribute("CameraHeight")), 0)
	Camera.CameraSubject = CameraBlock
end

local function CameraOffset()
	Humanoid.CameraOffset = (Head.CFrame + Vector3.new(0,1.5,0)):PointToObjectSpace(Head.CFrame.Position)
end

-- [ Code ] --
if CanRun then
	RunService:BindToRenderStep("Smooth Camera", 201, Loop)
end
