Shouldn't it say something like "capabilities: ... bluetooth ..."??

Re: Bluetooth not working - No adapters available (KDE)

On my machine with Bluetooth working properly I indeed have a Bluetooth wireless interface, with the bluetooth capability listed for the relevant device in the output of lshw:

❯ sudo lshw
...
              *-usb:3
                   description: Bluetooth wireless interface
                   vendor: Intel Corp.

                   version: 0.02
                   capabilities: bluetooth usb-2.01
                   configuration: driver=btusb maxpower=100mA speed=12Mbit/s
...

Does dmesg show anything useful?

Also, does rfkill show everything as unblocked?

❯ rfkill list

Re: Bluetooth not working - No adapters available (KDE)

I have a similar issue, I think.
hw: rog strix x470-i gaming
blueman manager claim no adapter is found
There's no mention of bluettoth in lshw or lspci
dmesg seems fine:
[ 7821.839528] Bluetooth: Core ver 2.22
[ 7821.839545] Bluetooth: HCI device and connection manager initialized
[ 7821.839548] Bluetooth: HCI socket layer initialized
[ 7821.839549] Bluetooth: L2CAP socket layer initialized
[ 7821.839551] Bluetooth: SCO socket layer initialized
[ 7830.880381] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[ 7830.880382] Bluetooth: BNEP filters: protocol multicast
[ 7830.880385] Bluetooth: BNEP socket layer initialized

In short, things seem to be as they should, only they are not.
Personally I haven't got a clue. I only hope the issue will fix itself, once I reinstall, which won't be too long.

NB,.
It has been working previously, the issue only appeared within the last week or so, presumable correlating with an update.

I am a philosopher, of sorts, not a troll or an imbecile.
My apologies that this is not always obvious, despite my best efforts.
