elementor: post blank when gallery is activated

Hi!

I’m just trying to build a web page and publish my first own post. I used Elementor to create it. It consists of a picture, a youtube video, text and a gallery with 27 pictures in the end.
The problem I’m facing is that the post appears blank when published if the gallery is activated. If I delete the gallery element (or use less pictures in it), everything is fine. If I publish it with all the images, the post looks fine as long as I’m editing it in Elementor but is blank when I look at it like a normal user.

I’ve cloned the post with a plugin to show you the difference.
here is the original post: /2019/11/02/ferrari-246-gt-spider/
here is the post with less pictures: /2019/11/03/ferrari-246-gt-spider-2/

I didn’t try where exactly the threshold is, since I want to be able to show as many pictures as I want..
I tried to increase the WP Memory Limit in wp_config.php to 512M but nothing changed..
Anyone an Idea what the problem could be?
