I cannot reproduce that, but I do experience something related: Bug 449178.

If you restart plasma with `plasmashell --replace` does the device list show up normally?

Comment 2 Benjamin Smith 2022-01-25 21:57:52 UTC

Yes, running `plasmashell --replace` repopulates the list. 

I think I see the relation of this bug to Bug 449178. Systemd probably turns off the Bluetooth on a suspend, then turns it back on upon wakeup, which triggers Bug 449178.

That makes a lot of sense.
