fwiw, I'm running into the same issue after restarting my IDE. It was working fine at EOD yesterday but started throwing the same error as above this morning.

Have a similar issue with no errors in the logs but still getting stuck on "Waiting for the app to load" in a "create-expo-app" project. It does build and run in an ios simulator normally with npx expo start. When I go to the link on http://127.0.0.1:55908/stream.mjpeg it does look like the app has started to load:

Environment
React Native IDE: v0.0.19
Expo: v51.0.22
React Native: v0.74.3

I installed cocoapods and the application builds without any issues, but the simulator gets stuck:

Thanks @nateyeazel for investigating this. Apparently the logs doesn't tell us much, but in the recent version we improved a couple of things and also added better logging. So I'd appreciate if you could try it again with 0.21 version and report if the issue still persist.

Also to avoid duplicates I'll be closing this one – please continue the discussion on #633
