How too disable a frame from appearing after death?

Hello, im not the best at scripting so bare with me.

Let's say there is 1 screengui in StarterGui, with 2 frames inside of it. 1 frame being the loading frame, then another frame being the Main Menu. I want the main menu too appear after someone dies, but not the loading screen so they dont have too wait for it too load again. I also followed a tutorial for this main menu + loading screen. The tutorial link is:

Main Handler Local Script- (Inside the ScreenGui)

local plr = game.Players.LocalPlayer

local char = plr.Character or plr.CharacterAdded:Wait()

What I would do is something quite simple. Create a bool that basically is set to true once the loading screen is loaded. That bool will prevent the screen from appearing after the player dies. Additionally, I created an if statement that will load the loading screen if loaded == false. If loaded == true, then it should not load the loading screen. Let me know if you have any issues!

local plr = game.Players.LocalPlayer

local char = plr.Character or plr.CharacterAdded:Wait()
char:WaitForChild("HumanoidRootPart").Anchored = true

local mouse = plr:GetMouse()
local loaded = false

local camera = workspace.CurrentCamera

camera.CameraType = Enum.CameraType.Scriptable
camera.CFrame = workspace.MenuComponents.CameraStartPosition.CFrame


local tweenService = game:GetService("TweenService")


local mainMenuGui = script.Parent


local mainMenuBG = mainMenuGui:WaitForChild("MainMenuBackground")

local playBtn = mainMenuBG:WaitForChild("PlayButton")
local creditsBtn = mainMenuBG:WaitForChild("CreditsButton")

local creditsBG = mainMenuBG:WaitForChild("CreditsBackground")


local loadingScreenBG = mainMenuGui:WaitForChild("LoadingScreenBackground")

local logo = loadingScreenBG:WaitForChild("Logo")

local loadingBarBG = loadingScreenBG:WaitForChild("LoadingBarBG")
local clippingFrame = loadingBarBG:WaitForChild("ClippingFrame")
local loadingBar = clippingFrame:WaitForChild("LoadingBar")


if loaded == false then
	clippingFrame.Size = UDim2.new(0, 0, 1, 0)

	clippingFrame:TweenSize(UDim2.new(1, 0, 1, 0), Enum.EasingDirection.InOut, Enum.EasingStyle.Quint, 5)
	
	
	clippingFrame:GetPropertyChangedSignal("Size"):Connect(function()   
	
	    loadingBar.Size = UDim2.new(1/clippingFrame.Size.X.Scale, 0, 1, 0)

Hello. Thank you for the response. Am I supposed too put anything , like a value in the screengui? If not, I replaced the script with yours, and when I reset the loading screen still shows up. I was trying to make it so the loading screen shows up when the player joins, but not after the player dies. I need it so only the main menu to show up after the character dies.
