Splash icon in android 12 is truncated

I am developing a splash screen using the library androidx.core:core-splashscreen.

As shown in the official documentation, the icon size of windowSplashScreenAnimatedIcon is set to 288x192, but when the app is run on an api level 31 or higher device, the icon appears to be truncated.

Is there any way to solve this?

[google splash guide]

[My themes.xml]

<style name="AppTheme.Splash" parent="Theme.SplashScreen">
    <item name="windowSplashScreenBackground">@color/color_aeaeae</item>
    <item name="windowSplashScreenAnimatedIcon">@drawable/splash_icon</item>
    <item name="postSplashScreenTheme">@style/AppTheme.NoActionBar</item>
</style>

[My splash_icon.xml]

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:width="288dp"
        android:height="288dp"
        android:drawable="@android:color/transparent"
        android:gravity="center" />

    <item
        android:width="192dp"
        android:height="192dp"
        android:drawable="@drawable/ic_baseline_sick"
        android:gravity="center" />
