alright, so just a couple of days ago I know that bluetooth on my manjaro system was working. Now however it is not.
to begin with it is not blocked (although now every time I reboot I have to unblock it)
rfkill list all 0: hci0: Bluetooth Soft blocked: no Hard blocked: no bluetoothctl isn't super felpful
bluetoothctl [bluetooth]# Agent registered [bluetooth]# show No default controller available [bluetooth]# list [bluetooth]# from what I can see there aren't any real issues in the bluetooth service

I've also tried installing some drivers (that I didn't need before)
yay -S rtl8821ce-dkms-git I've reinstalled everything related to bluez
And of course I've tried rebooting, but no luck
