@MajesticToday (cc: @rzeczyspisane ) like I said above bluetooth has been problematic for years. I am re-watching the video right now where Greg Kroah-Hartman (stable linux kernel maintainer) suggests that bluetooth drivers are one of the most volatile part of the kernel because the hardware is so brittle (he actually said it is so bad). And there is bluez, pipewire, etc. other layers that have a surface area for bugs.
It works for awhile and then it breaks in some small - but, important way.
Please adjust your expectations to rely on workarounds with which you find success. What works for me is to manually disconnect before the machine needs to sleep or I need to reboot.
For me simply restarting the bluetooth.service is not a 100% solution. Some times the hardware just needs a line-level reset - which requires a reboot without any device connected to it.
YMMV.
