An unknown error occurred when saving AI file
Since updating to 24.2 on our Macs people are intermittently getting "An unknown error occurred" when trying to save an AI file. We have found in those cases outlining all the fonts will let us save. We are using the latest version of Universal Type Client for our font management.
Thanks for reporting this issue, Illustrator Team really appreciate this.
We are unable to reproduce this issue in house. We need your help in getting this issue reproducible.

Please Also let us know if you have been using any 3rd Party plugin while facing this problem.
Since this is not a generic issue that we can reproduce at our end, we might need someone to look into your machine to figure out what is going on here.

I'm getting the same issue randomly throughout the day. Very frustrating
I'm having this issue too. I can no longer open those files either.
Had the same error today saving my files: unknown error while saving file
I had this problem today. It was font related but not Myriad Pro. A font, Frutiger light, which was not even being used and therefore not opened with other fonts but was listed missing under Type > Find Fonts. I changed it to a different font and the document saved.

I was having this same issue with the 2021 / 25.3.1 version and turning off Myriad Pro Regular in Suitcase fixed it. Thank you so much to Justin below, you saved me hours of troubleshooting!

Just an update we've found when this happens to us we can go into our font manager (Universal Type Client) and deactivate Myriad Pro Regular, and it will let us save afterwards.

Same issue here, whether its via external hard drive or internal ssd, i have both pc and imac pro / both of which encounter the error - my pc more than my imac however.

Same problem here in Windows 10, in July 2021.
This only happens when saving an AI file.
The only solution that worked for me is to reset Illustrator Perferences: Open up Illustrator holding CTRL+SHIFT+ALT.
Justin Taylor commented
Something common we've found is this happens on files with Myriad Pro. Our workaround has been changing to a different font so we can save the file, then clean the font cache and change the font back.

just updated to Big Sur this weekend on Mac. Was able to save my file periodically then was not able to.
Did open the file from a server that was still in the process of syncing. Also use Font Suitcase.
tried renaming, saving as different file types and locations (and back saving it). Nothing worked- lost 20 mins of work. Blank document with just square would not save either.
an unknown error has occurred illustrator
It can't be saved even just create a new file with 1 rectangle. also a blank new file can't be save.
Even Opening a blank doc. and saving with nothing in it results in An Unknown Error.
I just ran into the same problem on my PC. Using Suitcase. Even when font outlined... File will not save.
This isn't just a MAC issue, I have PC and just ran into this same issue. Thanks to your post, I was able to outline fonts and save just fine. I'm using Typekit.
