My camera and blur script doesn't work but also sometimes works for some reason??

I am trying to create a script about when the button is clicked, the camera goes back to the player and the blur is removed. However, the camera goes back to the player but doesn't remove the blur sometimes. The blur either goes away or just stays there for some reason, any help?

local cc = workspace.CurrentCamera
local pc = game.Workspace.MenuCamera
local pb = script.Parent.PlayButton

wait(.001)

cc.CameraType = Enum.CameraType.Scriptable 

cc.CFrame = pc.CFrame

local camera = game.Workspace.CurrentCamera

script.Parent.PlayButton.MouseButton1Click:Connect(function()
    game.Lighting.Blur.Enabled = false
    if game.Lighting.Blur.Enabled == true then
        game.Lighting.Blur.Enabled = false
    end
    wait(0.1)
    camera.CameraType = Enum.CameraType.Custom
    script.Parent.Enabled = false
end)
