Quest 3 passthrough black after developing with Unreal.

While I'm not a developer. I too have the issue where when I exit a game, the passthrough is just black.
I can see the menu, when I toggle passthrough, it goes into my virtual space, then toggle back to passthrough and it's the menu with black screen.

To fix it, I have to push the power button to put it to sleep(I think that's what a one press does). Then press the power again, and the passthrough comes back. 

I may have a defective unit though since when I look at my phone the phone looks all warped, and the phone is center frame .
