Having issues that I cannot wrap my head around on my Mac computer when running React Native. when trying to run 'npm run start' or 'npx react-native start'. I do not understand how I can run a certain project with the emulator and simulator, but other projects I try working on, I cannot get pass: reload, Dev_Menu, DevTools and the only message I get is 'warn no apps connected. Sending '' to all React Native apps failed. Make sure you app is running in the simulator or ...'

I run doctor and the only thing I can tell is a warning with 'Matro Builder is not running'

I've tried -reseting gradle cache

• tried running on a separate port 'npx-native start --port=8080'
• I've reinstalled watchman, npm

Anyone have any idea what could be the issue?

I tried creating a new React Project my init but I cannot get the app to connect to the emulator and simulator. I TRIED EVERYTHING
