Error when generating release AAB in React Native

I’m trying to publish my React Native app to the Google Play Store. I’ve generated a private signing key using keytool in C:Program FilesJavajdkx.x.x_xbin, and I’ve moved it to my project folder under android/app.

I set up my gradle variables under android/gradle.properties:

MYAPP_UPLOAD_STORE_FILE=my-upload-key.keystore
MYAPP_UPLOAD_KEY_ALIAS=my-key-alias
MYAPP_UPLOAD_STORE_PASSWORD=*****
MYAPP_UPLOAD_KEY_PASSWORD=*****

I’ve edited the file android/app/build.gradle and put the following text under signingConfigs:

signingConfigs {
        release {
            if (project.hasProperty('MYAPP_UPLOAD_STORE_FILE')) {
                storeFile file(MYAPP_UPLOAD_STORE_FILE)
                storePassword MYAPP_UPLOAD_STORE_PASSWORD
                keyAlias MYAPP_UPLOAD_KEY_ALIAS
                keyPassword MYAPP_UPLOAD_KEY_PASSWORD
            }
        }
    }

However, when I try to generate the release AAB using cd android ./gradlew bundleRelease, I get multiple errors:

1: Task failed with an exception.
-----------
* What went wrong:
Execution failed for task ':app:bundleReleaseResources'.
> A failure occurred while executing com.android.build.gradle.internal.res.Aapt2ProcessResourcesRunnable
   > Android resource linking failed

resource mipmap/ic_launcher_round (aka com.authentication:mipmap/ic_launcher_round) not found.
     error: failed processing manifest.

2: Task failed with an exception.
-----------
* What went wrong:
java.lang.StackOverflowError (no error message)

Does anybody have any idea what I’m doing wrong? Any help would be much appreciated!
