Unable to Scroll down the Page Until I Click on Expand

Hi I have a problem when I try to open certain pages on a website. The main page loads fine, but when I go to an article or category page and scroll down, there’s a message that says “click to expand.” The page gets stuck and doesn’t fully load unless I click on that message to expand the content. I didn’t make any changes to the website to cause this issue, and I’m not sure why it’s happening. I’m not sure if it’s related to Google AdSense, a problem with my web browser, or an issue with the WordPress plugins or theme or some some other issue. I really need to solve this problem quickly, so any help would be greatly appreciated. Thank you in advance.

It works fine on my end but if you need some support, you can contact the item author
