CLS (Cumulative Layout Shift) Form

Hello,
Some of my forms have no CLS (Cumulative Layout Shift) issues, while others do have CLS issues. Here are the example links. I am sure the issue comes from the form. How can we resolve this problem?

Also, it seems like the forms are being loaded onto the page later.
Thank you.

What causes this error?
