How do i make all GUIs disabled while the LoadingGUI is playing?

I made a loading assets Gui and when i play the other guis of the game appear with the Gui and it looks really bad, i wonder if there was a way that i could disable the other guis for 5 seconds or something like that, because i only want the loadingscreen for 5 seconds.

game:GetService("ReplicatedFirst"):RemoveDefaultLoadingScreen()
local cp = game:GetService("ContentProvider")
local optionalAssets = {}
local disabledServices = {
	["Lightning"] = false;
	
} --services not to preload
local ui = script:WaitForChild("laodingUI")
ui.Parent = game:GetService("Players").LocalPlayer:WaitForChild("PlayerGui")
local blur = Instance.new("BlurEffect", game:GetService("Workspace").CurrentCamera)


--preloading
warn("starting preload")
local startTick = tick()
--preload the optional assets first
cp:PreloadAsync(optionalAssets)

--preload the entire game

for i,service in pairs(game:GetChildren())do
	pcall(function()
		if not disabledServices[service.Name] then
			--warn("service not disabled")
			cp:PreloadAsync((service))
		end
	end)
end
wait(10)
warn("preload done, time:"..string.sub(tick()-startTick,1 ,5).."s")
ui:Destroy()
blur:Destroy()

There is a far easier way to do this. To accomplish what your trying to do AKA make only the loading screen visible, go to the loading screen's main frame. From there change the Zindex to 100. That means it will appear in front of all other GUIs, consequentially making them appear invisible. I hope I was able to help.
