Airpods pro staying on green

My airpods pro are staying on green, when i open them they stay green Then they start blinking. I cant connect to them so I tried disconnecting and re connecting but that made the problem worse. Now i try to hold the button on the back of the case but this doesn't do anything but make the green light flash more. This could be a problem due to one of my airpods being missing so i only have 1 airpod. But my airpods had been working for 3weeks with one airpod and all of a sudden it stops working. My airpods where on a charging station and when i got them they where kind of hot thats when I saw they couldn't connect. They are fully charged so this is not a battery problem.
