Bugs in content types

Steps to reproduce:

1. Create a Branching Scenario content with youtube video in it on the second page.(Not a page that loads initially)
2. In the 'view' page, open the content in full screen node.
3. Navigate to the page that contains the youtube video
4. The video will not show on the page. 

Platform: WordPress

Currently able to replicate on desktop for sure.

Browser: Chrome

H5P Plugin Version: 1.16.0

H5P content type and version: Branching Scenario - 1.8.2

Hi there,

instead of getting a H5P-Downlaod file, users on my Wordpress-website just getting some strange code.
https://www.schooltools.at/schooltools-h5p/musik-memory-2/

It also doesn't work with Edge, but it seems to work in Firefox.
The error appears in FE as well as in BE..

Any ideas?

Thank you in advance.

In 2022, I created a relatively complex and multi-part course as an ‘interactive book’ that I would now like to offer again. When updating some content, I received the following error message when saving: ‘count(): Argument #1 ($value) must be of type Countable|array, null given’.
