Hi SPNIOrganization,
Sorry you're running into this issue! @Robert_LeClair had a great point about what version of ArcGIS Pro you're using because that could affect your workaround.
If the data that you're using is a Service Layer, then it's possible that your issue is related to a bug that we addressed and fixed in Pro 3.0 (BUG-000138573).
If you're not using a Service Layer, the problem you are running into may be specific to your layout file. Can you contact Esri Support? They are better equipped to handle troubleshooting steps and gather bug data. They can be contacted at https://support.esri.com/en/contact-tech-support.
In the meantime, I encourage you to try a work around for the issue by exporting via the Python window instead of the export pane. You can learn more about exporting a layout via Python here https://pro.arcgis.com/en/pro-app/latest/arcpy/mapping/layout-class.htm
Here is a sample script you can paste in the Python window to export all layouts in a project to PDF.
##Export to PDF
import time
aprx = arcpy.mp.ArcGISProject("CURRENT")
aprx.listLayouts()
for lyt in aprx.listLayouts():
#Parameters: output name, resolution, image quality, compress vector graphics, image compression, embed fonts, layer attributes, georeference, jpeg compression, clip to elements, output as image, embed color profile
#Image quality: "BEST", "BETTER", "NORMAL", "FASTER", "FASTEST"
#Image compression: "ADAPTIVE", "DEFLATE", "JPEG", "LZW", "NONE", "RLE"
#Layer attributes: "LAYERS_ONLY", "LAYERS_AND_ATTRIBUTES", "NONE"
start = time.time()
lyt.exportToPDF(f"C:\Temp\{lyt.name}.pdf", 150, "BEST", True, "ADAPTIVE", True, "LAYERS_ONLY", True, 80, False, False, False)
end = time.time()
print(f"{lyt.name} exported in {end - start} seconds")
print("Done")
Hope this helped!
