I have had it happen on the Oculus Quest a few times where it will blacks the screen out and audio plays. I have found some of the time it is due to something in the background causing Aces High to get something pulled in front of it. I usually have to ALT + TAB out and make sure I click Aces High program and bring it to the front. Other times I have to plug the cord straight into my video card. For some reason it does not like to run off the motherboard
