Gui doesn't work in game, but works in roblox studio. How could i fix it?

When i run my game in roblox studio GUI works, but when i run it at the site after published - GUI doesn't work. All scripts are local.

I tried:

Make all scripts non-local

Check scripts work with print()

Replace all StarterGUI stuff to PlayerGUI

Change GUI ZindexBehavior

Change Frame Zindex

OpenCodesMenu script :

local Frame = GUI.CodesFrame
local button = script.Parent

OpenMenuStats script :

local PlayerGui = game.Players.LocalPlayer:WaitForChild("PlayerGui")
local PlayerUI = PlayerGui.PlayerUI
local button = PlayerUI.Buttons.Stats
local statsMenu = PlayerUI.StatsFrame
local hasOpen = false

PlayerUI.Enabled = true
statsMenu.Position = UDim2.new(2,0,.5,0)

button.MouseButton1Click:Connect(function()
	
	if not hasOpen then
		hasOpen = true
		statsMenu.Visible = true
		statsMenu:TweenPosition(UDim2.new(.8,0,.5,0))
	else if hasOpen then
			hasOpen = false
			statsMenu:TweenPosition(UDim2.new(2,0,.5,0))
			spawn(function()
				wait(1)
				statsMenu.Visible = true
			end)
		end
	end
end)

--i have found that sometimes, guis may not load instantly. this usually requires you to use waitforchild on variables that are declaring a gui instance such as:

local PlayerUI = PlayerGui.PlayerUI
local button = PlayerUI.Buttons.Stats
local statsMenu = PlayerUI.StatsFrame

-- change the above lines and any other gui-declaring variable to:

--[[
local instance = PlayerGui:WaitForChild("INSTANCENAME")
]]

-- in the case i showed the first time you would change it to:

local PlayerUI = PlayerGui:WaitForChild("PlayerUI")
local button = PlayerUI:WaitForChild("Buttons"):WaitForChild("Stats")
local statsMenu = PlayerUI:WaitForChild("StatsFrame")

-- if the solution above does not work, check the .visible property on the UI elements and check output for any errors by pressing f9
