Freeze on returning to game after adjusting volume in Oculus Home

Hi, we are having an issue where we can exit/enter the game without any problems by pressing the Xbox button. However if we adjust the volume or adjust the lens spacing, when we press the Xbox button again, we are greeted with a frozen unresponsive game.
we observed this with runtime 1.8.0.277202, one of our users for which it doesn't happen and behaves properly is still on  1.8.0.276585

Thanks
