Today Illustrator gives many errors: UKCO unknown. It happens with each step which I take. Newest version Mac, 27.8  So I cannot proceed. I saw in earlier posts (february) that this happened as well. Any solutions? Translation: the operation could not be completed due to an unknown error

Same here... Installed the previous version from the creative cloud app and now it's working fine.

Hi Everyone,

 

We understand the frustration you're facing with the "UKCO" error in Illustrator 27.8. The product team is aware of this issue and has already worked on a fix. You can expect the resolution in the next release. To stay updated and receive the fix, I recommend upvoting this UserVoice (https://illustrator.uservoice.com/forums/601447-illustrator-desktop-bugs/suggestions/47043832-illust...)

In the meantime, you can try a workaround by removing the "Vectorizing Presets" from the preferences folder. Please note that any custom presets created in the previous releases for image trace might not appear after deleting this file.

Preferences folder location:

Windows - " %AppData%\Adobe\Adobe Illustrator 27 Settings "

Copy & paste this location into the My PC address bar.

Mac - " ~/Library/Preferences/Adobe Illustrator 27 Settings "

 

Note: Location starting with this "~" sign indicates the User Library, which is hidden. So, you need to copy & paste the exact path in spotlight search or from Finder Menu > Go > Go to Folder > Paste the location in the dialog box like this:

 

 

If you have any other questions or need further assistance, feel free to ask. We appreciate your patience!

 

Best regards,
Anshul Saini

It's also possible to toggle the visibility of hidden files and folders by pressing Cmd+Shift+. when focussed on a Finder window (or in an "Open File/Save As..." dialogue).

Same here, I can't even open Illustrator since the v 27.8 update (in Australia) - I'm on a Mac Studio, latest OS, and I get the 

"The operation cannot complete because of an unknown error [UKCO]" message on trying to open it, even when opening from the creative cloud "Updated recently" screen.

Hi from Aus too, just got back in from lunch and it's gone bung on me same error. I think it's because I restarted earlier today morning, bc things were going strange across InDesign too. Bit annoying isn't it.

yep - reverting back to the previous version does fix this. Just worked for me. But really not great Adobe!

Opened illustrator for the first time in a week and instantly got the error message Error: the operation cannot complete because of an unknown error. (UKCO). I clicked ok and it continiued to load then the message popped up again. I haven't tried to do anything in illustrator yet but it keeps popping up. I've run a virus scan and restarted the laptop but no different. Does anyone know how I fix it? 

 

Thank you
