Interactive video embeddeed in Moodle plays only audio from YouTube

The H5P video player is not working when embedded in Moodle and trying to play youtube content. I have this setup in two different universities. The courses support open access.

I am testing this on a Mac using Safari, Edge, and Chrome: https://moodle.jyu.fi/mod/hvp/view.php?id=1526484 In Safari, the video does not work at all. Previously, I received an error message prompting me to watch the video on YouTube, which was related to cross-site tracking/scripting and Safari’s security features. It used to work in Edge and Chrome, but now both Edge and Chrome only play the audio track without video. The same issue occurs on Windows with Edge and Firefox. Safari and iPhone do not seem to play even the audio. This same issue also occurs in Aalto University's Moodle (https://mycourses.aalto.fi/mod/h5pactivity/view.php?id=1427911), so it seems that something is generally broken with the H5P Interactive Video – YouTube integration.

A student notified about this today. I have about 50 students working on the video content and I assume that this were reported when it was first encountered, so it is probably a new thing.
