Are you accessing network status in your application too? If so I think you need to include permission for this too in your manifest.

In my case with flutter, I had a similar error that was solved by adding android:exported="true" to the main activity, so in your case it seems to be here

<activity android:name=".Front" android:label="@string/app_name" android:exported="true">
