Background task panel appears when making a PDF from InDesign

[David232773055qwc]

When exporting a document from InDesign to make a high res PDF I get a background tasks warning panel saying failure to export to PDF. I've updated to most recent version of InDesign but still happening. I've also deleted pictures from the document to see if this helps. Still happening, can you help please?

What file types are linked?

Can you expand the Link Panel, so the file type and warnings are visible. Make a screensot and post it here.

Export the first half of the file. If it works, export the second half. Keep breaking it down until you find the problem

As @BobLevine mentioned, you need to figure out what page has the issue. Once you figure out the page, then you can figure out what on the page is the problematic thing. It could be a graphic, problematic font, text frame that's become corrupted, etc. Narrow it down until by process of elimination through deleting pages/objects).
