Issue with HMD power button click when HandTracking

I am doing a hand tracking project using tutorial project

with OculusQuest3, Ovr version 63.1 .

I bind my ‘OpenMenu’ function to left hand system menu click gesture(equals Gamepad_Special_Left), and everything okay but when I click my Oculus’s power button for screen off and re-click to get back to game, ‘OpenMenu’ function was never able to be called for a long time(it seems different every time)..

I found that Gamepad_Special_Left gesture input didn’t work in that situation.

And at the same time in the situation, when my real hand went out of the Quest3’s tracking camera, virtual hand went to origin not last virtual hand’s location.

What’s the possible problem?

Thanks
