Some feature images changes dimension after posting a new blog post

Question

I have posted a new blog. After that in my list of blogs I see the feature images of few posts have changed their dimension to 1 * 1 px. Attached is the snapshot of inspect, the first image which is the latest one has good feature image, but next post does have feature image but just the dimensions are 1*1 px. If you check my website, you will notice there are subsequent posts which have same dimension issue, few of them are good !!

I checked the media where dimensions are good and I have not changed them. I double checked and feature images for blog post is enabled. I uninstalled the jetpack which was one of the suggestion I got from WordPress forum while looking for similar issue.

Astra theme and editor plugin Elementor.

Is there something I am missing ?

Check out website where you will see the issue. Let me know if you need more information.
