3D FlipBook - "Please wait! The book is processing..."

Hi,

I cannot modify or create new books. I receive the message: "Please wait! The book is processing..." in Google Chrome and Brave, and "Setting up fake worker failed: 'e.at is not a function' (in 'e.at is undefined')" in Safari. New or modified 3D books appear blank on the blog page, while the existing books still display correctly.

I checked the forum and found a post from someone (2024-07-17) who encountered the same issue. He mentioned that he rolled back to version 1.15.2, and it worked again. In my case, I can only roll back to version 1.16.1 using WP Rollback.

Here is a link to my page: https://apprendreavecbobo.fr/cahier-de-lecture/

Thanks for your help
