I just updated my InDesign software to the most recent version (16.2.1) and now InDesign won't let me export files to PDF, whether it's interactive or print. The files I am trying to export, I have exported before so I know it's not a file size or image downsampling issue. I have restarted my computer, which did not help. I also uninstalled and reinstalled InDesign, which also did not help. I am on a MacBook Pro using macOS Mojave Version 10.14.6. Any help would be appreciated.
Before you do that - try resetting your preferences
The easiest way toreseteverything is todeletetheInDesign preferences: as soon asInDesignstarts to boot hold down Shift, Alt, Ctrl (and Apple/Cmd if working on a Macintosh). A dialog will appear asking todeletetheInDesign Preferences, select 'Yes' on this dialog.
If it's just 1 pdf - then I'd try to Export the file to IDML - open and save as an InDesign file - then try again.
