Video not playing inside <aricle> element

I hope someone can point me in the right direction.
On my page, YouTube videos do not play directly on the blog page when you are in the "" element.

Here is the site: https://biog-biogas.com/blog/

If I drag them out of the element in the inspector, or even if I click on the article I can play the videos normally.

I guess it’s just a CSS problem? But I just can’t figure it out. Already played around with z-index but unfortunately without success.

I am really grateful if someone could give me a tip.

Thanks and BR;
Niko

>Solution :

You have a restriction in pointer events in the css, remove it

Actual CSS

.post-entry-content {
  pointer-events: none;
}
