Description

Hallo, using,
"react": "19.1.4",
"react-native": "0.81.6",

Image

Since upgrading to the new Architecture , Metro has changed and it doesn't have the option to press A and rebuild the project again, so I used to just rerun again the process for the new Arch , but after some updates it stopped working and it says another processes is running at that port but its the same metro with the same project, does anyone have a clue? its abit annoying to try to kill it and rerun it again :p

Research direction

No files or tests are named. Start by reproducing the port-8081 conflict with React 19.1.4 and React Native 0.81.6 after enabling the New Architecture, then trace Metro's handling of an existing process; done means rerunning the same project no longer requires manually killing and restarting Metro.
