custom loading screen does not work?

i'm trying to make a custom loading screen which also shows a main menu screen, when i click play it doesn't show the loading screen and just shows the main menu. It's inside a localscript in ReplicatedFirst

local PlayerGui = game.Players.LocalPlayer:WaitForChild("PlayerGui")

PlayerGui:SetTopbarTransparency(0)
print("making thing")
--create screengui for loading screen
local screen = Instance.new("ScreenGui")
screen.Parent = PlayerGui
--create background image for loading screen
local image = Instance.new("ImageLabel")
image.Parent = screen
image.Size = UDim2.new({1, 0},{1, 0})
image.Image = "rbxgameasset://Images/impound"
image.ScaleType = "Crop"
--create text for loading screen
local text1 = Instance.new("TextLabel")
text1.Parent = screen
text1.Size = UDim2.new({0.292, 0},{0.136, 0})
text1.Position = UDim2.new({0.354, 0},{0.035, 0})
text1.BackgroundTransparency = 1
text1.Text = "Loading Assets"
text1.TextScaled = true
text1.Font = "SourceSansLight"
--create subtext for loading screen
local text2 = Instance.new("TextLabel")
text2.Parent = screen
text2.Size = UDim2.new({0.223, 0},{0.089, 0})
text2.Position = UDim2.new({0.388, 0},{0.251, 0})
text2.BackgroundTransparency=1
text2.Text = "This may take a second, Please be patient!"
text2.TextScaled = true
text1.Font = "SourceSansLight"
script.Parent:RemoveDefaultLoadingScreen()
wait(math.random(25,30))
screen.Parent = nil
--show the main menu
PlayerGui:SetTopbarTransparency(0)
local gui = PlayerGui:WaitForChild("MainMenu")
gui.MainMenu.Visible = true
gui.MainMenu.flyaway:Play()
--set the camera even though it doesn't work lol
game.Workspace.CurrentCamera.CameraType = "Scriptable"

game.Workspace.CurrentCamera.CFrame = CFrame.new(3380.12549, 444.000671, -2824.32593, -0.49998194, -0.224146292, 0.836526513, 0, 0.965925872, 0.258818746, -0.866035879, 0.129404694, -0.482945502)
