Solution

Add this style to your TextView and the problem should be solved:

style="@style/Theme.Material3.DynamicColors.Light"

Example

<TextView
            android:text="@string/testText"
      ----> style="@style/Theme.Material3.DynamicColors.Light" <-----
            android:layout_width="400dp"
            android:layout_height="50dp" app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintEnd_toEndOf="parent" android:id="@ id/textView"
            app:layout_constraintTop_toTopOf="parent" app:layout_constraintBottom_toBottomOf="parent"/>
