Metro bundler sometimes hangs on starting the dev server

[ritikkumar8z]

Hi React Native team 👋,

Sometimes when I run npx react-native start, the Metro bundler just hangs and doesn’t fully start — especially after switching branches or pulling updates. I usually have to clear cache with --reset-cache or restart the terminal to fix it.

Just wanted to ask if there’s a recommended fix or if this is something worth improving.

Thanks a lot for maintaining React Native! 😊

Hi @ritikkumar8z - do you know what stage it seems to hang at?

It’d handy to see the output if you run with DEBUG=Metro:* yarn start, and then try to start an app.
