As a Web Designer, no matter what I did, I could not fix the CLS problem in any way. I don't understand the difference between pagespeed inside CLS and chrome performance CLS. Also, I guess there is no benefit in delaying Adsense codes like “async”.

I would be very grateful if you can help me with this issue.

There's lots of detail here as to when those are different: https://web.dev/articles/optimize-cls#identifying-post-load-cls-issues

In particular I notice that when I scroll down your screen the lazy-loading images for the off-screen sections cause CLS as shown in the attached video.

Lighthouse does not scroll, so does not see this CLS.
