2020 M1 air here and airpods pro are waking my machine as soon as it goes to sleep. Some general bluetooth bugginess around I think.
You may want to try turning off automatic device switching for AirPods on that laptop to see if that helps.
Do you need wake on Bluetooth on? I find it more trouble than it’s worth.
This issue was killing my battery, but I don't use bluetooth on this laptop at all, so going to Settings > Bluetooth and turning it off completely fixed the issue for me. Haven't seen a bluetoothd process in ~2 weeks now.
I don’t think they will fix it, isn’t it searching for and proxy ink for AirTags?
