No bluetooth adapters found.

I performed ~sudo pacman -Syu yesterday and when my wireless headphones disconnected the bluetooth is no longer working.

Re: No bluetooth adapters found.

I have this exact same problem on 6.4.1-tkg, but I don't have it on 6.4.1-arch

Re: No bluetooth adapters found.

Did the kernel get updated?  Did you reboot?

Yep, I used linux-zen and it updated yesterday before this error occurred. I downgraded the kernel but still same. Then I switched to linux-lts but the problem still persists.

Re: No bluetooth adapters found.

It happened again! This time it just randomly crashed. I got this while launching blueberry:

ERROR:lib/bluez/adapter.c:165:adapter_get_dbus_object_path: assertion failed: (ADAPTER_IS(self))

(blueberry.py:1208): com.linuxmint.blueberry-WARNING **: 12:14:36.013: Could not retrieve the BT adapter name with 'bt-adapter -i': Command '['timeout', '2s', 'bt-adapter', '-i']' died with <Signals.SIGABRT: 6>.

also,

Re: No bluetooth adapters found.

Were there any kernel messages recorded in the journal when it happened again?  Please use code tags for commands and their outputs.
