I also also experiencing this on macOS. I am able to run the app as a macOS application. I can hit the frontend from the simulator safari. It shows the title for a quick second and then shows all white aside from the time and battery indicators.

I saw some errors about "View Controller" is unreachable with no entry points. I tried setting the view controller to "Is Initial View Controller" this stopped the warnings but did not get the application to initialize properly.

I can attach with a debugger but breaking doesn't get me anywhere of interest. I can say that it doesn't initialize properly when run from the command line without the --open too.
