Did you happen to ever get this to work for you?

For anyone that hit this issue of a black screen as well - its a simple, small fix and has nothing to do with the errors above: but the fix for me was to close the app that was launched from Xcode and manually launch it from your iPhone so it will ask for camera permissions, then relaunch the same app from Xcode and it fixes the black screen for me.. This did not fix any of the errors, but my planes were seen and the background mov was finally rendering - there was no error that said it was missing permissions so it was a small oversight and a quick and simple fix, however i do still hope for a resolution on the spam of errors above if anyone has any ideas, thank you
