Why my instance.new keeps going on forever when i clicked it?

I am making a test game and to test and spawn boss u need to click the button on the gui. However, i am having a trouble with the button "Delete all boss" i scripted it that it deletes the original folder and creates a new one Here is the script:

local ReplicatedStorage = game:GetService("ReplicatedStorage") 
local remoteEvent = ReplicatedStorage:WaitForChild("DeletezaBossu")
local ServerStorage = game:GetService("ServerStorage")
local Workspace = game:GetService("Workspace")
local Boss = game.Workspace.Boss


function onServerEvent(player)
    Boss:Destroy()
    wait(1)
    local Boss = Instance.new("Folder")
    Boss.Name = "Boss"
    Boss.Parent = Workspace

    end

remoteEvent.OnServerEvent:Connect(onServerEvent)

any help appreciated!
