Bluetoothctl scan on results in No default controller available

Help
1

Hello, I was recently messing with my configs after which my Bluetooth has stoped working, I have attempted to revert back but the issue persists for whatever reason.
When I attempted to scan for the Bluetooth devices with bluetoothctl scan on I get the following error.
No default controller available

Here is some information which I hope will be useful for debugging.

❯ systemctl status bluetooth

My config for Bluetooth

hardware.bluetooth = {
		enable = true;
		settings = {
			General = {
				Name = "Bluetooth_WOW";
				FastConnectable = "true";
				Experimental = "true";
			};
			Policy = {
				AutoEnable = "true";
			};
		};
	};

Powering off my system instead of restarting and booting into windows 10 has solved this issue .-.
I dont know how, I dont know why but now it works.

Can you tell us what network controller you have (lspci). Potentially, it doesn’t have great kernel support

My network controller is in my motherboard: ROG STRIX Z370-E GAMING
