Hmm, doesn't work for me, it is connected like usual, but the sound still doesn't go through.

With or without the BcrmPatchRam3.kext and BrcmBluetoothInjector.kext. The OS has to be playing sound for about 2~3 minutes for the AirPods to receive sound, but it's very delayed and robotic, flickering sound even. The Airpods play for a few seconds then go silent again. Changing playback apps also immediately stop sound transmission.

Interestingly, my left Airpod drains the battery quicker than the right one. Just a few minutes become L92%, R97%. The battery drain problem goes away when connected to the iPad. I think at this time, I better off using other earbuds.

Description
I have a similar issue too, but it's connected, just an output issue. Airpods Pro 2 only works when using hands-free mode or 8000Hz sample rate. 48KHz won't output sound at all. It was after the 13.5.2 update, it worked for a few seconds, then glitched out with a robotic sound, and then total silence. Tried to forget the device and pair it again, no output ever since. Other non apple Bluetooth sound devices works fine.
