How to fix UI not being recognized?

I am attempting to make UI have certain functions built into each UI element such as updating stats. The game I am making uses custom characters so I disabled character auto loads… When I disable character autoloads it causes my script to give the error "infinite yield possible on “SidebarUI.Main” Even though when I check in game my player gui has the correct UI’s loaded in. Here is my code

local Sidebar = {}

local Player = game.Players.LocalPlayer

local Character = Player.Character or Player.CharacterAdded:Wait()

local PlayerGui = Player:WaitForChild("PlayerGui")
local SidebarUI = PlayerGui:WaitForChild("SidebarUI")

local TweenService = game:GetService("TweenService")
local SoundService = game:GetService("SoundService")

--//FUNCTIONS
function Sidebar:updateCoins(newValue)
    SidebarUI.Main.Coins.CoinText.Text = newValue
end

function Sidebar:updateGems(newValue)
    SidebarUI.Main.Gems.GemText.Text = newValue
end

function Sidebar:updateEggs(newValue1, newValue2)
    SidebarUI.Main.Eggs.EggText.Text = newValue1.."/"..newValue2
end

function Sidebar:Tween(state, waitUntilFinished)
    local TweenPosition

    if state then
        TweenPosition = UDim2.new(0,0,0,0)
    else
        TweenPosition = UDim2.new(-1,0,0,0)
    end
    local tween = TweenService:Create(SidebarUI.Main, TweenInfo.new(1.5), {Position = TweenPosition})
    tween:Play()

    if waitUntilFinished then
        tween.Completed:Wait()
    end

    return true
end

--//BUTTONS
SidebarUI:WaitForChild("Main").SellButton.MouseButton1Click:Connect(function()
    SoundService.UI.OpenSoundEffect:Play()
    Character.HumanoidRootPart.CFrame = CFrame.new(-5.899, 8.277, -33.903)
end)

return Sidebar

Here is a photo of my current UI setup in a live game where I got the error

Can you show us what the error is (in the output)

It is what I stated above “Infinite yield possible”.

It is because the object was already there before it tried to look for it, you should probably just write this instead.

local SidebarUI = PlayerGui:FindFirstChild("SidebarUI")
