When I export to a pdf it crashes on large files. It worked last week.
Resource issues can be more subtle than sheer quantity, and app- rather than system-related.
I am betting on an incompatible image file in the project, though.
Adobe uploaded a new version of InDesign yesterday. The new version worked as expected and generated a new pdf without complaint.
You have to make sure, that all needed files are offline available. With right mouse click you can trigger files on an online server to become offline available.
everything is locally available.
Did you try to use the package option?
Indesign 18.0 has solved the problem. It was a bug.
Could have also been another fault that was 'fixable' but solved by the update (overwriting a corrupt file, etc.) If the process had never worked, I'd agree it might have been an app bug; that it stopped working points to something like a corrupted preference, cache, or the like.
But good that the problem disappeared, one way or the other!
It also didn't work on a different poster with a different set of images. I haven't tried redoing that yet but I expect it will work now.
