Thank you for reaching out to us.
Actual issue was in the code snippet for themes.xml file (in the values-night directory).

Correct code snippet:
<item name="android:statusBarColor" tools:targetApi="l">@color/colorPrimaryVariant</item>

Color used for android:statusBarColor is colorPrimaryVariant not status_bar_night.

Solution code for your reference:

Thank you so much for reporting this issue. This is fixed and will be published soon.
Hope this helps!
