Scanning for bluetooth devices never finds any devices

Edit: It works now and I have no idea why.

Hi all. I’m trying to connect my bluetooth headset to my desktop but scanning for devices, with KDE Plasma or bluetoothctl, doesn’t show any devices. My phone isn’t found either. I’m dual booting Windows and everything works fine there. I’m using NixOS. My bluetooth dongle shows up as “Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)”. Here’s what I found on systemctl status bluetooth

Any help is appreciated!
