Can someone help me with this player left message?

So, I made a code where if you joined message pop-up in chat that worked Ok, But how about the left message. I tried multiple times and it didn't work what's wrong with it?

This script in ServerScriptService

local MessageEvent = game.ReplicatedStorage.PlayerLeftMessageEvent

game.Players.PlayerRemoving:Connect(function(Player)
	repeat wait() until Player.Character or Player.CharacterRemoving:Wait()
 local text = "{System} "..Player.Name..", Has left to the game"
    local color = Color3.fromRGB(255,0,0)
	    local font = Enum.Font.Cartoon
   MessageEvent:FireAllClients(text,color,font)	
end)

What wrong with that's it's not working??

This for StarterGUI

local StarterGui = game:GetService("StarterGui")
local MessageEvent = game.ReplicatedStorage.PlayerLeftMessageEvent

 
MessageEvent.OnClientEvent:Connect(function(text,color,font)
    StarterGui:SetCore("ChatMakeSystemMessage",{
        Text = text,
        Color = color,
        Font = font
    })
end)

On line 4, you put:

repeat wait() until Player.Character or Player.CharacterRemoving:Wait()

Your script is probably waiting infinitely here, hence why any of the code isn't running.

You don't really have to put this line into your code, as once the player removes they're essentially already removed from the game. There is no point in calling the character after.
