Answer 1

This solution worked for me. Add the below mentioned code in the build.gradle file under android/app

    dependencies {
        // implementation "com.facebook.react:react-native:+"  // From node_modules
        implementation ("com.facebook.react:react-native:0.64.2") {
            force = true;
        }
   
    }
    

    apply from: file("../../node_modules/@react-native-community/cli-platform-android/native_modules.gradle"); applyNativeModulesAppBuildGradle(project)
    

configurations.all {
        resolutionStrategy {
            force 'androidx.core:core:1.6.0'
            force 'androidx.core:core-ktx:1.6.0'
        }
    }

Updating from react-native@0.64.0 to react-native@0.64.4 worked for me with this same issue.
