I had made a Layout with Map series pages in version 2.8.2 and now the project will no longer export the Map Series after updating to 2.9. Clicking Export on this layout with the map series causes ArcGIS Pro 2.9 to crash to the desktop. A different layout in this project exports just fine and doesn't contain a Map Series. I have played with the compression settings and tried exporting as something that isn't a PDF.
Is anybody else having this issue?
I would report it to ESRI Tech Support but the error reporting tool that pops up when Pro crashes is refusing to send the error report too.
