Solution

In your manifest, add android:exported="true".

example:

<activity
        android:name="com.example.packssas.MainActivity"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
