I may need you to backup your library under Settings->Backup and Restore->Backup Library, upload that to the cloud (Dropbox, Google Drive, OneDrive, etc) and share a link with mike@zubersoft.com. There are no known issues with exporting with the latest update, and I can't reproduce any crashes with exporting annotations, so we will have to see if there is something corrupted in your library that needs to be addressed. Otherwise you can also try uninstalling, reinstalling and then restoring the library backup to see if that fixes it (if it's some kind of issue with the PDF library files, for example). 

Thanks,
Mike
