Script preventing character from loading?

I made a custom chat script, but every time i enter the game to test it it stays on "Waiting for Character," and I'm wondering if theres something in the script thats causing it.

Script:

function UpdateOldLabels(Parent)
    for i,v in pairs(Parent:GetChildren()) do
        if v.Name:sub(1,4):lower() == "line" then
            local LineNumber = v.Name:sub(5)
            if LineNumber == "12" then
                v:Destroy()
            else
                v.Name = "line"..tostring(tonumber(LineNumber) + 1)
                v.Position = v.Position - UDim2.new(0,0,0,15)
            end
        end
    end
end
 
game:GetService("Players").PlayerAdded:connect(function(player)
    player.Chatted:connect(function(msg)
        for _,v in ipairs(game:GetService("Players"):GetChildren()) do
            UpdateOldLabels(v:WaitForChild("PlayerGui").ScreenGui.Frame)
            newchatline = Instance.new("TextLabel",v:WaitForChild("PlayerGui").ScreenGui.Frame)
            newchatline.Text = player.Name.. ": " ..msg
            newchatline.Size = UDim2.new(1,0,0,15)
            newchatline.Position = UDim2.new(0,0,1,-15)
            newchatline.Font = "SourceSans"
            newchatline.TextColor3 = Color3.new(random)
            newchatline.TextStrokeTransparency = 0.8
			newchatline.TextStrokeColor3 = Color3.new(random)
            newchatline.BackgroundTransparency = 1
            newchatline.BorderSizePixel = 0
            newchatline.FontSize = "Size24"
            newchatline.TextXAlignment = "Left"
            newchatline.TextYAlignment = "Top"
            newchatline.ClipsDescendants = true
            newchatline.Name = "line1"
        end
        UpdateOldLabels(game:GetService("StarterGui").ScreenGui.Frame)
        newchatline:Clone().Parent = game:GetService("StarterGui").ScreenGui.Frame
    end)
end)

There is nothing in this script to cause that, go to players in studio, and make sure that the 'CharacterAutoLoads' option is checked.

scripts start before the player enters, therefore the script doesnt find any players so it wont work

try this

repeat 
wait()
until player

HA! He took it from my Custom Chat that's why its not loading he doesn't have a GUI that has a Frame inside to make it work that's why its killing you because its not a correct script.

He clearly just took it from my Script that I asked a question for
