I already tried that and it didn't work 😞
Is it just this document or any document (old or newly created)?
It's a new one. I'm trying page by page... I think it's a gif/png/jpeg that have an error but I cant understand which one it is
Try half the book - then try the other half
Whatever side it fails on is the problem - then keep halving.
It's a quick process to find the page.
