In the Meta Quest 2 virtual reality

Hello and may the mercy and blessings of Allah be upon you. Meta Quest 2 I've had it for almost two years. It doesn't have any issues except for what I'm about to tell you. Everything works perfectly except the left hand controller, which isn't functioning. I don't know why. Can you fix it? What comes with it?
