Server freezes when I refresh my scoreboard?

Hello,

I've run into a bug with my kitpvp plugin, it freezes the server everytime I refresh the scoreboard.

Code:

   
    @SuppressWarnings("deprecation")
    public static void ScoreBoard(Player p){
        int kst = Main.getInstance().getConfig().getInt(p.getUniqueId() + ".streak");
        int k = Main.getInstance().getConfig().getInt(p.getUniqueId() + ".kills");
        int d = Main.getInstance().getConfig().getInt(p.getUniqueId() + ".deaths");
        int tokens = Main.getInstance().getConfig().getInt(p.getUniqueId() + ".tokens");
        ScoreboardManager sbm = Bukkit.getScoreboardManager();
        org.bukkit.scoreboard.Scoreboard ingame = sbm.getNewScoreboard();
        Objective stats = ingame.registerNewObjective("stats", "dummy");
        stats.setDisplaySlot(DisplaySlot.SIDEBAR);
        stats.setDisplayName(ChatColor.GOLD + "" + ChatColor.BOLD + "SHOCKMC");
        Score kills = stats.getScore(Bukkit.getOfflinePlayer(ChatColor.BOLD + "" + ChatColor.GREEN + "Kills" + ChatColor.BLUE));
        Score kills1 = stats.getScore(Bukkit.getOfflinePlayer(ChatColor.WHITE + "" + k + ChatColor.AQUA));
        Score deaths = stats.getScore(Bukkit.getOfflinePlayer(ChatColor.BOLD + "" + ChatColor.RED + "Deaths" + ChatColor.GRAY));
        Score deaths1 = stats.getScore(Bukkit.getOfflinePlayer(ChatColor.WHITE + "" + d + ChatColor.DARK_PURPLE));
        Score streak = stats.getScore(Bukkit.getOfflinePlayer(ChatColor.BOLD + "" + ChatColor.YELLOW + "Killstreak" + ChatColor.GREEN));
        Score streak1 = stats.getScore(Bukkit.getOfflinePlayer(ChatColor.WHITE + "" + kst + ChatColor.BLUE));
        Score t = stats.getScore(Bukkit.getOfflinePlayer(ChatColor.BOLD + "" + ChatColor.DARK_GREEN + "Tokens"));
        Score t1 = stats.getScore(Bukkit.getOfflinePlayer(ChatColor.WHITE + "" + tokens));
        Score kit = stats.getScore(Bukkit.getOfflinePlayer(ChatColor.BOLD + "" + ChatColor.GREEN + "Kit"));
        Score kit1 = stats.getScore(Bukkit.getOfflinePlayer(ChatColor.WHITE + "" + Main.getInstance().player.get(p)));
       
        kills.setScore(14);
        kills1.setScore(13);
        deaths.setScore(11);
        deaths1.setScore(10);
        streak.setScore(8);
        streak1.setScore(7);
        t.setScore(5);
        t1.setScore(4);
        kit.setScore(2);
        kit1.setScore(1);
        p.setScoreboard(ingame);
    }
