Solved The compass does not open gui

Hi, I'm trying to make a plugin who teleport you in another bungeecord linked server but my compass does not open the gui with the server list any idea ?

Code (Java):

package comp;

import java.io.ByteArrayOutputStream;
import java.io.DataOutputStream;
import java.io.IOException;

import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.inventory.InventoryClickEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;

public class pllistenner implements Listener {

    private Main main;
   
   

    public pllistenner(Main main) {
        this.main = main;
    }
    @EventHandler
    public void onJoin(PlayerJoinEvent event) {
        Player player = event.getPlayer();
        player.getInventory().clear();
        ItemStack custw =  new ItemStack(Material.COMPASS);
        ItemMeta custv = custw.getItemMeta();
        custv.setDisplayName("Server Selector");
        custw.setItemMeta(custv);
        player.getInventory().addItem(custw);
        player.updateInventory();
    }
    @EventHandler
    public void onInteract(PlayerInteractEvent event) {
        ItemStack current = event.getItem();
        Player Player = event.getPlayer();
        if(current == null) return;
        if(current.getType() == Material.COMPASS && current.hasItemMeta() && current.getItemMeta().hasDisplayName() && current.getItemMeta().getDisplayName().equalsIgnoreCase("Server Selector"))
        {
            Inventory inv = Bukkit.createInventory(null, 9, "Server Selector");
            inv.setItem(3, new ItemStack(Material.OBSIDIAN));
            inv.setItem(4, new ItemStack(Material.COMMAND));
            inv.setItem(5, new ItemStack(Material.GRASS));
       
            Player.openInventory(inv);      
        }
    }
    @EventHandler
    public void onClick(InventoryClickEvent eventt) {
       
        Inventory invc = eventt.getInventory();
        Player player = (Player) eventt.getWhoClicked();
        ItemStack used = eventt.getCurrentItem();
       
        if(invc.getName().equalsIgnoreCase("Server Selector") && used.getType() == Material.OBSIDIAN)
        {
            ByteArrayOutputStream b = new ByteArrayOutputStream();
            DataOutputStream out = new DataOutputStream(b);
           
            try{
                out.writeUTF("Connect");
                out.writeUTF("Lobby");
            }catch (IOException e) {
                e.printStackTrace();
            }
           
            player.sendPluginMessage(main, "BungeeCord", b.toByteArray());
        }  

        else if(invc.getName().equalsIgnoreCase("Server Selector") && used.getType() == Material.COMMAND)
        {
            eventt.setCancelled(true);
            //player.chat("/server Dev");
        }
        else if(invc.getName().equalsIgnoreCase("Server Selector") && used.getType() == Material.GRASS)
        {
            eventt.setCancelled(true);
            //player.chat("/server Survivial");
        }
}
}
