sound:Play() on line 77 keeps looping no matter what I do?

Recently I have taken up the hobby of coding; however it has been a rough start. Thanks to this forum's help, I have been able to script an almost working Summon script for a game. Just as a tested the script for the last run, I ran into a problem where the script loops itself even though function has ended. I figured out somewhat that the problem may be coming from the IsTyping command as nothing happens when I move; however I have now idea how to fix it as I have only been coding for 2 or 3 days and the script is an amalgamation of multiple tutorials and solutions. How do I fix this problem.

Here is the code if it helps (Problem targets: Lines 77 and 13)

local UIS = game:GetService('UserInputService')
local plr = game.Players.LocalPlayer 
local Char = plr.Character or plr.CharacterAdded:Wait()

local key = 'L'

local Anim = Instance.new("Animation")
Anim.AnimationId = 'rbxassetid://4906894017'

local Debounce = true

UIS.InputBegan:Connect (function(Input, IsTyping)
	if IsTyping then return 
		
	end
	local KeyPressed = Input.KeyCode
	if KeyPressed == Enum.KeyCode.L and Debounce then
		Debounce = false
		local LoadAnimation = Char.Humanoid:LoadAnimation(Anim)
		LoadAnimation:play()
		print("The Crimson God Has Been Summoned; Run...")
		local CrimGod = true
		
		-- KONO DIO DA
		
		if CrimGod == true then
	local sound1 = game.Workspace.ChargeUp

	
	wait(2)
	
	sound1:Play()
	local orb = game.Workspace.Part
	
	if orb then
   		local player = game.Players.LocalPlayer
    local character = player.Character or player.CharacterAdded:wait()
    orb.Shape = "Cylinder"
    orb.Material = "Neon"
    local weld = Instance.new("WeldConstraint")
    weld.Parent = workspace
    weld.Part0 = orb
    weld.Part1 = character.HumanoidRootPart
    if player.Character:FindFirstChild("Torso") == nil then --checks to see if player is r15
        orb.Position = Vector3.new (player.Character.LowerTorso.Position.X,player.Character.LowerTorso.Position.Y,player.Character.LowerTorso.Position.Z)
    else --this is what happens if r6
        orb.Position = Vector3.new (player.Character.Torso.Position.X,player.Character.Torso.Position.Y,player.Character.Torso.Position.Z)
    end
end
end
