Why does my kill animation play in studio but not in the game?

I have a kill script which is set up if you press K, it plays an animation and you die. When I published and tested the game, it only killed me. I don't understand why the animation isn't playing. Can anyone help?

Script:

local Player = game.Players.LocalPlayer
local Character = Player.Character or script.Parent
local Humanoid = Character.Humanoid
local UserInputService = game:GetService("UserInputService")
local AnimationId = 'rbxassetid://4506927840'
local Debounce = true
local Key = 'K'
local noise = game.SoundService.Snap
UserInputService.InputBegan:Connect(function(Input, IsTyping)
    if IsTyping then return end
    if Input.KeyCode == Enum.KeyCode[Key] and Debounce == true then
        Debounce = false
        local Animation = Instance.new("Animation")
        Animation.AnimationId = AnimationId
        local LoadAnimation = Humanoid:LoadAnimation(Animation)
        LoadAnimation:Play()
        wait(0.4)       
        noise:Play()
        wait(0.2)   
        LoadAnimation:Destroy()
        Humanoid.Health = 0
        Debounce = true
    end
end)
