My left AirPod Pro suddenly stop working. HELP

My left AirPod Pro suddenly stop working. It is charged as best as I can tell. I have tried resetting the Airpods twice now--only the right one works. When I say it doesn't work, I mean that the left AirPod does not connect to either of my devices. I have an iPhone and a Mac. I was using both of them last night just fine. I woke up to the left one simply not connecting.
