Infinite yield possible on HumanoidRootPart?

So It works, the block and parry and more but when you died 1 time the sword will not work anymore. It says Infinite yield possible on HumanoidRootPart after dying 1 time. pls help me how to fix this

here the code:

local sword = script.Parent
local attackRemote = script:WaitForChild("Attack")
local blockRemote = script:WaitForChild("Block")
local player = game.Players.LocalPlayer
local char = player.Character or player.CharacterAdded:Wait()

local hum = char:WaitForChild("Humanoid")

local HumRP = char:WaitForChild ("HumanoidRootPart")

local anims = script:WaitForChild("Anims")
local equippedIdle = hum:LoadAnimation(anims:FindFirstChild("IdleEquipped"))

local RS = game:GetService("ReplicatedStorage")
local UIS = game:GetService("UserInputService")
local TS = game:GetService("TweenService")


local Modules = RS:WaitForChild("Modules")
local Remotes = RS:WaitForChild("Remotes")

local runRemote = Remotes:WaitForChild("Run")
local equipRemote = Remotes:WaitForChild("Equip")

local RaycastHitbox = require(Modules:WaitForChild("RaycastHitboxV4"))

local Combo = 1
local DoingCombo = 0

local M1Debounce = false

local isEquipped = false

local Animations = script:WaitForChild("Animations")

local blockIdle = hum:LoadAnimation(Animations:FindFirstChild("BlockIdle"))

local CanBlock = true


local isBlocking = player:WaitForChild("isBlocking")

local m1CDs = {
    [1] = 0.50,
    [2] = 0.33,
    [3] = 0.45,
    [4] = 1
}

local m1HT = {
    [1] = 0.33,
    [2] = 0.33,
    [3] = 0.33,
    [4] = 0.33
}

local m1HitStartDelay = {
    [1] = 0.17,
    [2] = 0.17,
    [3] = 0.17,
    [4] = 0.17
}

local m1HitDuration = {
    [1] = 0.18,
    [2] = 0.18,
    [3] = 0.18,
    [4] = 0.18
}

local M1Animations = {
    [1] = hum:LoadAnimation(Animations:WaitForChild("Attack1")),
