Yep! Same issue on both my M1 MBA and an Intel Mac Mini. On the Mini, even without it going to sleep, sometime after booting up, it will lose ability to connect to HomePod or AirPods. I suspect this is also Bluetooth related. These issues definitely started happening after upgrading to 12.3. Sigh.... I honestly don't remember when was the last time I had an Apple software release without any annoying issues that affected day-to-day use! Probably 5+ years ago.
