Answer 1

It could be a compatibility issue. Try running
npm install npm#latest -g
and check again

Answer 2

I think there was a mistake in your package.json. It should be a package name following it's version. In this case it's should be
"dependencies": {
"#react-navigation/native": "^6.0.13",
"expo": "~46.0.9",
"expo-status-bar": "~1.4.0",
"react": "18.0.0",
"react-native": "0.69.5",
"react-native-screens": "~3.15.0",
"react-native-safe-area-context": "4.3.1",
"react-navigation/native-stack": "^6.9.0"
},
