Installation and server related problems

I've recently got a lot of problems after updating the h5p plugin and their libraries. I am using H5P 1.15.3 running on Wordpress 5.7.2

One of them is: the Course Presentation Editor doesn't work at all.  I am getting this code [field:group:coursepresentation:presentation] instead of editable presentation. The browser console  (Chrome, Firefox) shows me a bunch of error messages like " Uncaught TypeError: Cannot read property 'prototype' of undefined..."

I would try to reinstall the plugin. how can I prevent losing the created content? 

Hi,
I am currently using H5P for a University projcet. I did an integration in wordpress but therefor, I need the tool "documentation" to save the goals I type in. 
Actually it makes no sense, to retype it every time I open the space:( Does anybody have a solution for that issue?
Thanks a lot in advance !

Hi 

We are having issues with Interactive video while trying to add a video using Macs and some browsers, the add video form does not display. Until we can identify the issue consistantly we want to prevent our WordPress 5.7.2 users from downloading the Interactive Video library. H5P version 1.15.2

Can this be done?
