I am having the exact same issue. Only left side and still 100% charged. Is it possible it's a software problem? Is your airpods pro case blinking orange when the lid is open? Not sure where went wrong but it just dead out of nowhere.

Update: I tried pairing with only left side and I found that it has a different firmware with the right one. Seems like this is the problem. I’m waiting for it to update itself now, pairing only left one to my phone.

Update 2: left it overnight and now it’s blinking green and not even showing up when I pair it. Lol. Heading to authorised store later to see if they can fix it.

Update 3: diagnostic says left side got problem, either casing or the bud itself got problem but he don’t have any extra casing to test. I’ll test it out with my friend casing next week and see if it helps. Otherwise then it’s dead.

Update 4: I turned off auto ear detection, connect to my left AirPods, put the airpod in my case and play music then it’ll work for some reason (just a couple of second of music and then it disconnects). I think the battery kaput/circuitry got problem already even though it’s showing 100% and I haven’t had any battery drain problem prior to this. I think I’ll just leave it overnight a couple of days outside of case and see if it’ll completely drain the AirPods before recharging it again. If still doesn’t work then I’m gonna treat it as dead.

Original replacement? A lot fake buds out there.
