Wordpress 6.1 - h5p - Keeps loading

Dear all,

I installed h5p (1.5.4 via Wordpress plugin) according to your guide on https://h5p.org/documentation/setup/wordpress

I can get to the site where I can create new content. I click on "multiple choice" and "use" I end with the text "loading". It seems as if the plugin cannot go further.

I re-installed everything, I even tried to install the plugin manually. But I cannot get it to work. Do you know what the problem is? What can I provide to narrow down the problem so that we find a proper solution? :-)

Kind regards
