Airpod Pros Gen 2 Not Playing Sound

I initially noticed that my left Airpod had static/crackling whenever I would move around; for example, whenever I was literally just walking around, I would hear static/crackle but if I just sat still, it worked fine. Next day, the left Airpod just stopped playing any sound whatsoever. What's weird is that the Airpod itself is fully charged but not only that, whenever I swipe up or down to control the volume, my phone seems to register the fact that I'm trying to change volumes using the Airpods so the buttons are still functional and I can even change modes using it, but still no sound however high I go. I have an Apple Watch SE that I tried connecting it to plus I even tried connecting it to a Windows 11 PC but I still had the same issue.

I looked all over the internet and did the standard cleaning; from Q-tips to even using tape to try to get a deeper clean but still nothing. Then I performed several factory resets with the whole "putting Airpods in case and holding button till it turned white to amber to white again" but still nothing.

Are there anything else I'm missing because I really just don't feeling like paying a premuim to get a repair done for 1 Airpod.
