Help, I can't export a doc, I get this massage "1 problem was found with a background task: failed to export the PDF file" thats it, I don't know what could go wrong, all the links works and restarting the program did'nt help
Try the divide and conquer approach.
Export half the doc and then the other. Which ever half causes the issue, split in half again until you find the problem page.
