    You need to have Flipper installed on your desktop/laptop. This way, when you try to debug your app, it will launch the debugger in Flipper instead of launching it in Chrome.

    You can read more about this and the deprecation warning in the official docs: https://reactnative.dev/docs/debugging#opening-the-debugger

    Has there been any update on this? I’m facing the same problem, I’ve upgraded my react-native app from 73.1 to 0.74.1. The react native documentation says they are removing the default integration with Flipper, but it is still trying to open Flipper when you Open the debugger from the Dev Menu, this makes it very unclear.
    I’m also having problems with the experimental debugger, since it is not being able to connect, the options I have remaining is using another debugger like reactotron, but I’d rather solve this first though.
