AI not responding while saving the PDF

Hi @sri_saravana_mills_9562,

Thanks for sharing the screenshots. Could you please confirm which version of Illustrator and Windows you're using? Also, let me know if this happens only when saving as a PDF or with other formats as well. Please confirm where you’re saving the file, locally on your system drive or to a network or cloud location. If it's local, try saving a copy with a different name or location and see if the process completes. You can also try turning off 'Preserve Illustrator Editing Capabilities' in the PDF save settings to check if that helps.

If the issue continues, please share the approximate file size and whether this happens with all files or only specific ones, so I can look into it further.

Looking forward to your update.
Abhishek
