attempt to index nil with 'HumanoidRootPart' ?

I Want players in a table to teleport in a specific position. But, the output says that HumanoidRootPart Is Nil.

And I have made a table and saw,

[1] = Brioche_Noodle [2] = "*** cycle table reference detected ***"

Function That I am focusing on,

function spawnMap()
	local Maps = Storage.Maps:GetChildren()
	chosenMap = Maps[math.random(1, #Maps)]
	
	chosenMap:Clone()
	chosenMap.Parent = workspace.Map
	
	
	for _, player in ipairs(Playing) do
		if player then
			print(player)
			player.Character.HumanoidRootPart.Position = Vector3.new(chosenMap.Teleporter.Position)
		end
	end

end

Here is my whole script.

local Players = game:GetService("Players")
local Teams = game:GetService("Teams")
local Storage = game:GetService("ServerStorage")

local Playing = {}
local NotPlaying = {}
local Infected = {}

local Team = {
	Lobby = Teams.Lobby,
	Infected = Teams.Infected,
	Citizens = Teams.Citizens
}
local gameStarted = false
local chosenMap

local function onPlayerAdded(player)
	print(player.Name .. " || Joined || ")
	
	if gameStarted == false then 
		print(player.Name .. " is added to The Playing Table")

		table.insert(Playing, player)
		print(Playing)
	else
		print(player.Name .. " is added to The Not Playing Table")

		table.insert(NotPlaying, player)
		print(NotPlaying)
	end
	player.Team = Team.Lobby
end



local function addPlayerToPlaying()
	local AllPlayers = Players:GetPlayers()
	
	table.insert(Playing, Playing)
end

local function addPlayerToNotPlaying()
	local AllPlayers = Players:GetPlayers()

	table.insert(NotPlaying, Playing)
end

function spawnMap()
	local Maps = Storage.Maps:GetChildren()
	chosenMap = Maps[math.random(1, #Maps)]
	
	chosenMap:Clone()
	chosenMap.Parent = workspace.Map
	
	
	for _, player in ipairs(Playing) do
		if player then
			print(player)
			player.Character.HumanoidRootPart.Position = Vector3.new(chosenMap.Teleporter.Position)
		end
	end

end

function despawnMap()
	local Maps = Storage.Maps:GetChildren()
	chosenMap.Parent = nil
	
	for _, player in ipairs(Playing) do
		if player then
			player.CharacterAdded:Connect(function(Character)
				Character.HumanoidRootPart.Position = Vector3.new(chosenMap.Lobby.Teleporter.Position)
			end)
		end
	end
	
end

while true do
	gameStarted = false	
	
	wait(4)
	
	gameStarted = true
	addPlayerToPlaying()
	spawnMap()
	wait(10)
	despawnMap()
	
	Playing = nil
	NotPlaying = nil
	Infected = nil
end

You need to check the player's character still exists as well as the player
