My right airpod pro isn't working, please help!

It's been nearly a year since i brought my airpods pro and they were working just fine until a few days ago, when the right airpod wasn't working. By that I mean, there wasn't any sound coming from it and it wasn't functioning at all. Before that happened, the left airpod wasn't working, but then I disconnected and reconnected and it worked fine again. I even tried connecting it to other devices, but the right aoirpod wasn't working. I tried charging it overnight, hoping it might just be a slight battery charge issue, but it still wasn't working. Please tell me if this is a hardware or software problem and how can I fix this.
