Broken Image on "Posts" page

Hello, I’ve got an odd issue. Whenever I designate a page for posts I get a broken image instead of my featured image. When I remove the post designation the correct image reappears, but as soon as I dedicate the page to posts again the broken image comes back. Any idea what might be causing this?

Hi there

Hope you are having a good day and thank you for your question
Can you please deactivate jetpack module for lazy image loading feature?

Thanks!
