Hi!
I ran into the following problem:
When using BT headphones, the sound disappears at one moment, and after a few seconds the connection disappears. After that, no device can be connected.
The main This happens consistently once a day. Rebooting doesn't help. It is necessary to completely turn off the system (poweroff) and turn it on.
I am sure that the hardware is fully functional, since there were no such problems on Win 11
System is up to date

Make sure and double check fast boot is disabled in Windows and reboot twice for vodoo reasons.

Windows is not installed on my laptop. I encountered this problem, installed Windows, checked that everything was working properly, and installed Arch ("clean" installation) back.
I also usually connect via KDE.
