What is causing local scripts to break on player death/respawn?

I am using multiple local scripts in my game to get player input and give the player an immediate response to certain actions, such as hiding in bushes or using abilities. However, after the player dies once in a live server, both of these scripts break, causing the player to only move and preventing them from going invisible or using their dodge roll ability, and after making many changes to the code I still do not understand where this problem is being caused in these scripts or how to fix it. Can anyone help tell me why? Here is the code that handles these events in case it helps: Variables / object identification

local Players = game:getService("Players")
local Player = game.Players.LocalPlayer
local RunService = game:GetService("RunService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local player = script.Parent
local root = player:WaitForChild("HumanoidRootPart")
local notInBush = player:WaitForChild("notInBush")
local isShooting = player:WaitForChild("isShooting")
local isHit = player:WaitForChild("isHit")

Player.CharacterAdded:Connect(function(Char)
	player = Char
	root = Char:WaitForChild("HumanoidRootPart")
	notInBush = player:WaitForChild("notInBush")
	isShooting = player:WaitForChild("isShooting")
	isHit = player:WaitForChild("isHit")
end)

Invisibility collision handling

function hideInBush()
	local head = player:FindFirstChild("Head")
	local face = head:FindFirstChild("face")
	for _, object in ipairs(player:GetChildren()) do
		if object:IsA("Accessory") then
			object.Handle.Transparency = 1
		elseif object:IsA("BasePart") and not (object.Name == "HumanoidRootPart") then
			object.Transparency = 1
		end
	end
	face.Transparency = 1
	hideInBushEvent:FireServer(player)
	notInBush.Value = false
end

function leaveBush()
	local head = player:FindFirstChild("Head")
	local face = head:FindFirstChild("face")
	for _, object in ipairs(player:GetChildren()) do
		if object:IsA("Accessory") then
			object.Handle.Transparency = 0
		elseif object:IsA("BasePart") and not (object.Name == "HumanoidRootPart") then
			object.Transparency = 0
		end
	end
	face.Transparency = 0
	leaveBushEvent:FireServer(player)
	notInBush.Value = true
end

Roll ability

function dodgeRoll(actionName, userInputState, inputObject)
	local cameraCFrame = workspace.CurrentCamera.CFrame
	if userInputState == Enum.UserInputState.Begin and canShootAbility and notShootingAbility == true then
		abilityCharges = abilityCharges - 1
		abilityAmmoUpdateEvent:FireServer(abilityCharges)
		notShootingAbility = false
		local dodgeInvoke = dodgeRollEvent:InvokeServer(movementKeys[0], movementKeys[2], movementKeys[3], movementKeys[1], cameraCFrame)
		notShootingAbility = true
	end
end

Thanks in advance
