Right Earbud not working

I have been using Earfun Air Pro 2 earbuds for well over a year now. These are incredible and have helped me a great deal with work - until recently. Out of the blue, the right earbud has stopped working completely. I have tried everything; putting both the buds back in the case, unpairing and repairing etc. The light on the right earbud still comes on though. When I press the reset button on the charging case with the buds in, only the left one blinks quickly while the right one blinks lazily. It is almost as if it has lost all connection with the case and the left airbud. While listening to music or YouTube, if I remove my left airbud, the music/video automatically pauses, while removing the right airbud does nothing (it used to before). Any clue regarding what it could be? Any remedies? I really don't want to lose out on these incredible babies.
