Outlining text results in "Can't finish previewing, Could not complete the requested operation."
I have found a number of posts talking about the error message but none associated with trying to outline text. All solutions point to a lack of RAM as the issue or an issue with the Illustrator build (25.4.1).
I don't think RAM is my issue , especially as I have tried the above process with only Illustrator running.

As ever I have a print deadline today with no way of getting the file out that adheres to the printers requests.
Any thoughts, MUCH appreciated.
