When you export you see the process, maybe page 11 is proceeded. So go to page 12 and look into the link panel, open the images and check them. Maybe it is an image there, open it in Photoshop, saves as (not only save) again to rewrite the structure of the image. If it can't be opened, check why. Is it damaged, replace it with another version, is it not available try to synchronize the file from the server.

You see the page where it stops or takes longer than expeted. Go to that page, to the previous or next page too,
In my experience the most problems show up, when EPS or SVG are use, which are not supposed to be part of print projects.
