Empty upper part of the layout (near the toolbar and status bar)

I have a problem with the design layout in Android Studio, when designing the layout there, the layout looks acceptable and everything okay, but as soon as I run it forms a very nasty white area between the Status Bar and the Toolbar (although I do not use the Toolbar), and the theme which is applied (Theme.MaterialComponents.Light.NoActionBar), does not imply the presence of ActionBar. In any case, I must admit that my skills and experience in Android development is not enough to solve this problem, I would be glad for any help, thanks in advance.

I attach the code of the layout:

    <?xml version="1.0" encoding="utf-8"?>
     <androidx.constraintlayout.widget.ConstraintLayout    
     xmlns:android="http://schemas.android.com/apk/res/android"

     android:layout_width="match_parent"
     android:layout_height="match_parent"
     tools:context=".activities.WelcomeActivity">

    <ImageView

        app:layout_constraintTop_toTopOf="parent"
        app:srcCompat="@drawable/background_intro" />

        android:textSize="41sp"
        app:layout_constraintEnd_toEndOf="parent"

        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/btnLogin" />

</androidx.constraintlayout.widget.ConstraintLayout>

I tried to use android:fitsSystemWindows="true" but it had no effect, unfortunately I could not find any other cases with this problem, I also tried to activate Fullscreen mode.

But this also had no effect, which is needed.
