Trouble with camera distortion

Hi. So I just discovered that Camera distortion is possible on Roblox so I decided to try it. I found this simple “tutorial” about camera distortion, but every time I run the game my character keeps dying.

Code:

local Run = game:GetService("RunService")

local Cam = game.Workspace.Camera
local distortion = CFrame.new(0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0)

Run.RenderStepped:Connect(function()
    Cam.CFrame = Cam.CFrame * distortion
end)
