Running the app with react-native cli has a black screen

🐛 Bug Report

Summary of Issue

When running the app with react-native start, my app doesn’t get past a black screen. It starts up with my launch screen but changes to a back screen as soon as the green loading bar starts. After loading gets to 100%, the green bar goes away and the app stays black even though I can see a console log from the root App.tsx file.

Expected Behavior vs Actual Behavior

I would expect the app to run with the normal splash screen that it has when running with expo.

I have a hunch that this is related to expo splash screen but not sure. The app loads up just fine with expo start and runs just fine with a production build. Some things I have done to debug:

• Removed everything from App.tsx except a View (and console log)
• Ran expo init for a new bare test app and used the same versions it had for all the starting packages
• Matched the metro.config, babel.config, and app.json with the bare test app
• Reset the sim
• Cleaned the xcode build folder
• Restarted my machine (swinging for the fences on this one)
• Copied the SplashScreen, SplashScreenBackground, and SplashScreen.storyboard from the bare test app
• Tested a physical device

Has anyone run into this or have any more suggestions on how to debug?

I might have found something interesting at least. In my effort to make everything exactly the same as the working test app I have, I copied the info.plist over and it was finally able to show the initial app screen. Looks like this config is the culprit:

<key>UIApplicationSceneManifest</key>
	<dict>
		<key>UIApplicationSupportsMultipleScenes</key>
		<true/>
	</dict>

Not sure where I got that or why it breaks things but I am guessing I have something configured incorrectly.
