unabletocopy on wordpress

Hello, team,

I have a huge problem! All my activities have stopped working and show blank on my website. I'm not sure when it started. I have updated all the libraries and installed all the updates, and it's still not working. I've attached screenshots of what I'm seeing.

I can see the content in the h5p list, but when I click the title, it's blank. When I click edit, I'm able to see all the activities and content is there, I'm able to edit and make changes, but when I press update, it gives me the error "unabletocopy". If I click edit again, the changes have been made. 

I'm using WordPress version 6.9.1; 

It's happening on all browsers I've tried;

it's happening on mobile and desktop; 

H5P plugin version 1.17.1;

All content types that I use, and I mostly use interactive book, single choice set, drag the words, drag the images, dialogues and accordion;

Forgive me, I don't know how to check the errors; 

Screenshots are attached;

I removed the plugin Jetpack Boost recently and installed ShortPixel;

No changes to the browsers that I'm aware of;

Please help! How can I fix this?

Here is an example of post where I have an h5p activity and it's just blank where it says "test your comprehension" https://thesoundsofportuguese.com/quem-e-quem-patreon/

Thank you so much in advance.
