As the Error Message says:

Android resource linking failed the files that are present in the values folder might not properly be linked up with AndroidManifest files

Check if the files present in values folder string, style, color, etc are properly mapped in AndroidManifest.xml

If no, then Map it.

Then run the following commands: cd android ./gradlew clean cd .. and then run: react-native run-android --variant=release

For me I had accidentally deleted android/app/src/main/res/values/strings.xml and android/app/src/main/res/values/styles.xml when replacing the app icons. Adding them back in fixed it.

Example strings.xml:

<resources>
    <string name="app_name">APP_NAME</string>
</resources>

Example styles.xml:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="android:textColor">#000000</item>
    </style>

</resources>
