When trying to enable Bluetooth, nothing happens.

Actions:
- Search bluetooth
- Open bluetooth settings
- Click 'on' button
- Button switches but interface sticks to 'bluetooth turned off'

rfkill list shows no blocks, sometimes a softblock
rfkill unblock all lifts softblock but behavior persists (no functioning bluetooth)
