controller/hands not detecting after headset unmount for few secs

Hi I'm using both hands and controller for a mixed reality application. I'm using unity 2022.3.21f1 with meta all in one xr sdk and oculus. when headset unmount or power button is pressed, the headset doesn't recognize hands nor controller. I'm using both controller as well as hands for interaction. any one know any fix for this issue ? Thanks in advance.
