Layout keep crashing when I want to download the file in PDF. I have tried a lot of things for 2 hours and it starts to drive me crazy.
Can you share the LayOut file?
Something somewhere might be corrupt. To locate it you can try exporting one page at a time. A corrupt font might also be the culprit.
If you open the LayOut file and go to File/Document Setup… look at the Rendering setting. If the Override box is checked, uncheck that, and then see if exporting PDF is fast.
