unity compile oculus quest app but only black screen appears

Also been starting to see this problem (with 2019.4.4f1 and the latest Oculus Integration Asset). I first saw the issue about a week ago but at the time there was also a new version of the Oculus Integration Asset that had just been published and when I upgraded the issue seemed to fix itself. Maybe it was somehow a bit of a coincidence that it apparently fixed itself last week - maybe it wasn't related to the new version of the asset. Now I'm already on the latest version of the asset I'm not sure what to try and this is stopping me from being able to share test builds of my application on the Quest :(
