Asset Export – Unable to export message – Solution
Using Version 23.1.1 — Today, I experienced this error on one specific file of a handful of similar AI files. Performing the same process on each file: converting a very simple group of artwork into an Asset Export item, exporting SVG and PNG versions with my preferred settings all with great success. When I got to one file in the group, it repeatedly gave me this message while trying to export svg and png alike...

After lots of troubleshooting, the problem was the directory to which I was saving the file. I have no idea what broke or what Illustrator decided not to like about this folder (must be some unseen file going on there), but nothing obvious was the culprit.
Fix: Save to a different folder then move them in manually. Hope this saves another AI pro some time.
