14:20:24.271 - LoadAnimation requires the Humanoid object ! Why Doesn't My Script Work?

This Is a knife Tool Script I made (A local Script)

I Have It in StarterPack

When I Run It The First Time , The Animation Is Properly Loaded

But When I Die and Respawn The "Second" Time , It Presents Me With This Error ...

" 14:20:24.271 - LoadAnimation requires the Humanoid object (Tizzel40.Humanoid) to be a descendant of the game object"

[ It errors At Line 29 When I try To Load My Animation ! ]

And Guess What , It also Prints "HUM IS A DEC OF THE GAME OBJ !" too , which I find Wired For It to not to work !

Why Is It Broken , what Does This Mean , And How Do I Fix it ???

Here is a local script , located inside a folder , inside my tool. The Folder is Named "Scripts" !

local play = game.Players.LocalPlayer

local mouse = play:GetMouse()

local char = play.Character

if not char then
	char =  play.CharacterAdded:Wait()
	end
	
		
local hum = char:WaitForChild("Humanoid")


repeat wait() until hum:IsDescendantOf(char) 

warn("HUM IS A DEC OF THE GAME OBJ !")

local tool = script.Parent.Parent

local Using = tool:WaitForChild("Using")

local Animations = tool:WaitForChild("Animations")
local Scripts = tool:WaitForChild("Scripts")
local Remotes = tool:WaitForChild("Remotes")

local Stats = require(Scripts.Stats)

local TakeOutKifeAnimation = hum:LoadAnimation(Animations.TakeOut)
