when I run the script everything works for about three rounds in the game. will you help?

It gives me this error " ServerScriptService.Game:41: attempt to index nil with 'Name' " the line that isn't working is this line here 41 or 23 here : Status.Value = ChosenMap.Name.." Chosen"

-- Define Variables

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local ServerStorage = game:GetService("ServerStorage")

local MapsFolder = ServerStorage:WaitForChild("Maps")

local Status = ReplicatedStorage:WaitForChild("Status")

local GameLength = 15

local reward = 25

--Game Loop

while true do
	
	Status.Value = "Waiting for enough players"
	
	repeat wait(1) until game.Players.NumPlayers >= 1
	
	Status.Value = "Intermission"
	
	wait(15)
	
	local plrs = {}
	
	for i, player in pairs(game.Players:GetPlayers()) do
		if player then
			table.insert(plrs,player) -- Add each player into plrs table
		end
	end
	
	wait(5)
	
	local AvailableMaps = MapsFolder:GetChildren()
	
	local ChosenMap = AvailableMaps[math.random(1, 2)]
	
	Status.Value = ChosenMap.Name.." Chosen"
	
	local ClonedMap = ChosenMap
	ClonedMap.Parent = workspace

You didn't clone the chosen map. You are supposed to clone the chosen map so that it can be used next time for another round.
