bluetoothctl: No default controller available

I am getting a No default controller available error while using bluetoothctl:

$ bluetoothctl
Agent registered
[bluetooth]# show
No default controller available

What I already did:

• when I try to use blue devil and click on enable, it doesn't enable and clicking it does nothing.

• both bluez and bluez-utils are installed.

• rfkill list all shows both acer-bluetooth and hci0 as unblocked.

• sudo bluetoothctl also shows the same "No default controller available".

• I am already a part of the lp group.

the Bluetooth service is enabled:

$ systemctl status bluetooth
