Description
React Native Debugger app version: 0.9.10
React Native version: EXPO SDK 34
Platform: IOS
Is real device of platform: No
Operating System: macOS High Sierra
Everytime I open React Native Debugger, it works for a few seconds and then I got a red screen showing "Runtime is not ready for debugging. Make sure Packager server is running"
Not sure why, the app runs okay if I turned off React Native Debugging. I don't have any other alternative since react-devtools is not working anymore. I need to inspect the element and fix the layout.

Thanks

Research direction
Start by reproducing the red “Runtime is not ready for debugging” screen with React Native Debugger 0.9.10, Expo SDK 34, an iOS simulator, and macOS High Sierra. Check the debugger’s runtime connection and packager interaction; done means React Native debugging remains usable without the error while the app is running.
