Intel AX200 bluetooth and wifi suddenly not working in Linux GNOME

Symptom

You can’t toggle bluetooth on/off in GNOME applets.

rfkill list show bluetooth is not blocked.

bluetoothctl list show empty bluetooth controller list.

Solution

sudo modprobe -r btusb
sudo modprobe btusb

This will unload and reload btusb module, which may be able to fix the issue.
