Bugs in content types

We can create questionnaires, but they don't display in a public facing (or preview) of a post or page. I included the requested details below. But the short of it is that I'm getting this message in the console when I load the page.

Uncaught TypeError: Cannot read properties of undefined (reading 'library')

I look forward to your guidance in resolving this problem.

Bug report:

To show interactive video in course page in Moodle, without enter in activity page, I use iframe:

<iframe src="https://myMoodleSite.it/mod/hvp/embed.php?id=xxxx" allowfullscreen="allowfullscreen" style="border: 0;"></iframe>

This way the video is in two nested iframes, one is mine and one is that of h5p.

Please someone who can help me solve this problem. Thanks and regards
