Export artboard to PDF crashes

I believe it is since the latest update, but can't verify that - every time I try to export my artboard to PDF it starts for about 2 seconds and then crashes totally.  Tried renaming the files to shorter file names, tried replacing the "FIX" files in the presets/scripts that I use so that the file size is not enormous back to the original files. Nothing helps.  Crashes regardless of whether I try to export one or more artboards. Crashes regardless of whether I use a zip output or not.

Please help.  This function worked perfectly prior to the update and it is a crucial part of my workflow.

Thanks!
