I got same issue here while building android

Task :react-native-safe-area-context:compileDebugKotlin
w: file:///D:/work/template-0.75-stable/template-0.75-stable/template/node_modules/react-native-safe-area-context/android/src/main/java/com/th3rdwave/safeareacontext/SafeAreaView.kt:59:23 'getter for uiImplementation: UIImplementation!' is deprecated. Deprecated in Java

env:
"react": "18.3.1", "react-native": "0.75.5", "react-native-safe-area-context": "^5.3.0", "react-native-screens": "4.10.0",

and downgrade didn't work.
I think it should be a bug, since i just use npm install and then build went wrong.

This err didn't occur after i added Ninja which required by another package.
