Can't display image at all in drupal 9

In my custom twig template I insert:

<div id="hero_response">

In CSS Selector for background image I put #hero_response. Image is not displayed.
I tried with class = "hero_response" and .hero_response in CSS selector, but it not works at all.
I also insert responsive image style which works on other fields in template.

I have same problems with
Background Images Formatter →
and my issue is here https://www.drupal.org/project/bg_image_formatter/issues/3202586 🐛 Can't display image at all in drupal 9 Active

Could it be something with my configuration?

Please help
