I had a user with a 37 page Indesign document that had become corrupted when Indesign had crashed. We could open the document, but if we scrolled down beyond We tried the Indesign auto recovery, but it would just cause Indesign to crash again.
The way I fixed the document was By exporting it to an “InDesign Interchange” document by going into the file menu and then choosing export.
I then shut down Indesign, re-opened it and then opened up the Indesign interchange document that I had just exported. When I loaded the document it then imported lots of the images and was usable again!.
