How to fix the non-existent blank SplashScreen issue on Google Play Console?

Question

I am facing an issue of Android compatibility that warns me that there is a double splash screen, which is not true. I checked my implemenation and did not find any double splash screen. Also, there is only one splash screen to see when the app gets started.

Here is, how I implemented: themes.xml

<resources>

    <style name="Theme.<App_Name>" parent="android:Theme.Material.Light.NoActionBar" />

     <style name="Theme.<App_Name>.SplashScreen" parent="Theme.SplashScreen">

         <item name="postSplashScreenTheme">@style/Theme.<App_Name></item>
         <item name="windowSplashScreenBackground">@android:color/white</item>
         <item name="windowSplashScreenAnimatedIcon">@drawable/ic_launcher_foreground</item>

         <item name="android:windowLightStatusBar">true</item>
    </style>
</resources>

My AndroidManifest.xml:

<application
    android:allowBackup="true"
    android:dataExtractionRules="@xml/data_extraction_rules"
    android:enableOnBackInvokedCallback="true"
    android:fullBackupContent="@xml/backup_rules"
    android:hardwareAccelerated="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:localeConfig="@xml/locales_config"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/Theme.<App_Name>.SplashScreen"
    tools:targetApi="tiramisu">
    <activity
        android:name=".activities.MainActivity"
        android:exported="true"
        android:hardwareAccelerated="true"
        android:theme="@style/Theme.<App_Name>"
        android:windowSoftInputMode="adjustResize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

My MainActivity:

class MainActivity : ComponentActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        var isSplash = true

        installSplashScreen().setKeepOnScreenCondition { isSplash }

        Handler(Looper.getMainLooper()).postDelayed({ isSplash = false }, 800)

        // ...
    }
}

Splash screen dependency version:

implementation("androidx.core:core-splashscreen:1.0.1") // The latest one.

Why does Play console warns that there is a doble splash screen? This warning appered in my very recent release upload. I had not that in previus releases.
