Not working under Filtering..?

Why doesn't this code work with FilteringEnabled? It works when you join the game, then when you die and respawn, it doesn't work anymore.

repeat wait() until game:GetService("Players").LocalPlayer

local Player = game:GetService("Players").LocalPlayer
local Character = Player.Character or Player.CharacterAdded:wait()
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Timer = ReplicatedStorage:WaitForChild("Timer")
local MapHolder = workspace:WaitForChild("MapHolder")
local SelectedMap = ReplicatedStorage:WaitForChild("SelectedMap")
local Playing = Player:WaitForChild("Playing")

local CurrentCamera = workspace.CurrentCamera

Angle = 0
while wait() do
    if Timer.Value > 0 and Playing.Value == false and Character:FindFirstChild("Humanoid") and Character:FindFirstChild("Humanoid").Health > 0 then
        CurrentCamera.CameraSubject = MapHolder:FindFirstChild(SelectedMap.Value):FindFirstChild("PartCAM")
        CurrentCamera.CoordinateFrame = CFrame.new(MapHolder:FindFirstChild(SelectedMap.Value):FindFirstChild("PartCAM").Position) * CFrame.Angles(0, Angle, 0) * CFrame.new(0, 0, -25)
    elseif Timer.Value < 0 and Playing.Value == false and Character:FindFirstChild("Humanoid") and Character:FindFirstChild("Humanoid").Health > 0 then
        CurrentCamera.CoordinateFrame = CFrame.new(workspace.Scene:FindFirstChild("PartCAM").Position) * CFrame.Angles(0, Angle, 0) * CFrame.new(0, 0, -10)
        CurrentCamera.CameraSubject = workspace.Scene:FindFirstChild("PartCAM")
    elseif Timer.Value > 0 and Playing.Value == true and Character:FindFirstChild("Humanoid") and Character:FindFirstChild("Humanoid").Health > 0 then
        CurrentCamera.CameraSubject = Character:FindFirstChild("Humanoid")
    end
    Angle = Angle + math.rad(0.5)
end
