Right AirPod Pro is being recognized by the charging case, but it will not connect to any of my devices.

My AirPods were working perfectly fine the day before yesterday, but yesterday when I tried to use them, the right AirPod wouldn't pair with my iPhone. I tried using it with my iPad but it didn’t pair with that either, or with my Mac.

At that point I factory reset them (forgot them, opened and held the button until it flashed amber) and then reconnected. Despite this only the left one connected.

After that I reset my phones settings and made sure my phone was updated and it still didn’t connect. I checked the firmware for the AirPods and it was also up to date.

I assumed it might’ve been a charging issue (even though they were charging perfectly fine the day before yesterday), and cleaned the tips and the charging port, but it still didn’t work.

I believe the right AirPod is being recognized, it just won’t connect. When I put the left AirPod into the charging case, it flashes green. When I remove both AirPods the charging case also flashes green. But when I put just the right AirPod in the case, it just continuously flashes white, and I’ve attached a photo of what my phone shows.

I didn’t know what to do at this point and just left them alone overnight, but it’s still not working. Has anyone ever experienced anything similar? Any help would be much appreciated!
