I am connecting a Pixel 3A to my Macbook Pro 2018 model.

I have tried resetting the SMC, resetting the PRAM, putting both devices in safe mode and re-pairing, deleting .plist files (globally and for account), resetting bluetoothd, etc.

Whenever I pair the device it is successful but then when I click connect it just immediately goes from Connected to Not Connected.

I looked in Console for bluetoothd process and found that this occurs when the device tries to connect and then goes to Not Connected state.

default 14:36:09.265542-0800    bluetoothd  ***** [BluetoothHCIEventNotificationMessage] kBluetoothHCIEventDisconnectionComplete
default 14:36:09.265572-0800    bluetoothd     EVENT:  DisconnectionComplete
default 14:36:09.265598-0800    bluetoothd  EVENT: Disconnection Complete: Reason = 19

Followed by <device name> has no service mask by AirPlayXPCHelper.

I've also reason reason 22 as well.

This post states that the error codes fall within the 0x012 – 0x7F Reserved for future use. range so I am not sure what to make of it.

Any suggestions to help debug/fix this? I am at a standstill at the moment.
