The mysterious "Unknown Error"

[#1]

Mac Catalina 10.15.6

Illustrator 24.2.3

I keep getting the "An unknown error has occurred" when I try to save my work as an AI or PDF file. Its not 100% of the time, but when it happens I have to reboot my machine to get it to work again. I saw on previous threads about hidden or locked layers so I unsuccessfully tried that. I just uninstalled and reinstalled Illustrator and that didn't work either. I have no embedded images - its just vector shapes and some text. The artboard is fairly large (110" x 121") Some help would be greatly appreciated

Are the fonts checked and 100% OK? What kind of fonts are they?

Do you use font management and is it compatible?

Where do you save files? Is "Save in background" turned on or off? Can you turn it off?

Is there a printer installed, turned on and set up as the default printer? Is the printer driver up to date? If there are other printers installed, are they available at all times?

Hi there,

Sorry about this trouble. I am hopeful that the issue was fixed. If not, we have recently released an update for Illustrator 2020 (v 24.3) which contains some stability fixes. If you are not already on v24.3, then we recommend you to update to latest version.

If that doesn't help, try steps shared on this link and share your observations with us.

Regards,

Srishti
