Probably the controller firmware needs updating after a recent headset update. Usually in this case you have to use hand tracking to control the white dot to sign in to your profile when you reboot the headset. Or move your head to point the white dot at your profile image then briefly press the power button to "click" on it. Once logged in to your home environment, the controller firmware should update automatically. Or if you have the Meta Quest Link app installed on your PC, then you might be able to update the controller firmware from the Devices tab. You can also try using the MetaHorizon+ app on your phone to pair the controllers.
