BroadcastMessage from event

I have this code. When i try to use it on my 1.14 server, i get this error:

Caused by: java.lang.IllegalStateException: BroadcastMessageEvent cannot be triggered asynchronously from another thread.

I have been using it prevously on 1.13, but now it wont work. Any ideas?

Code:

@EventHandler
    public void onPlayerChat(AsyncPlayerChatEvent e){
        if(pl.muted.contains(e.getPlayer().getUniqueId().toString())){
            e.setCancelled(true);
            e.getPlayer().sendMessage(ChatColor.RED + "You are muted!");
            return;
        }       
       
        Bukkit.broadcastMessage(pl.players.get(e.getPlayer().getUniqueId().toString()).rank.color + pl.players.get(e.getPlayer().getUniqueId().toString()).rank.prefix + (pl.players.get(e.getPlayer().getUniqueId().toString()).rank.id < Rank.SPONSOR.id ? ""  : ChatColor.DARK_GRAY + " ┃ " ) + pl.players.get(e.getPlayer().getUniqueId().toString()).rank.color +
                e.getPlayer().getName() + ChatColor.GRAY + " » " + ChatColor.WHITE +
                (pl.players.get(e.getPlayer().getUniqueId().toString()).rank.id > Rank.BRUKER.id ? ChatColor.translateAlternateColorCodes('&', e.getMessage()) : e.getMessage()));
        addLog(e.getPlayer().getName() + ": " + e.getMessage());
        e.setCancelled(true);

    }
