Error Opening CorelDRAW .ai Files After Illustrator Update

The problem is the current version of Illustrator will not open Illustrator .AI files exported from CorelDRAW if the exported file has any live text objects in it. That error box "Illustrator could partially read this file" will be displayed. If all the objects are just vector shapes, including text objects converted to curves, the file will open successfully.

Obviously the current work-around is having a previous version of Illustrator installed alongside the current version. If the CorelDRAW-generated .AI file is re-saved in Illustrator 28.7.7 it will then open in Illustrator 29.5. This work-around is going to be good for only so long. In a few months version 28 builds will no longer be available to download/install once Illustrator 30 is released.

There is something about the text objects in .AI files exported from CorelDRAW that Illustrator just does not like. Prior to this current error where the exported .AI file wouldn't open there were other problems. Text objects created in CorelDRAW would have all sorts of line spacing issues when brought into Illustrator. Point text objects with multiple lines of copy would have hardly any line spacing at all. Area text objects would have line spacing that is dramatically reduced. These issues still exist when opening a Corel-exported .AI file in Illustrator 28.7.7. Usually I fix this problem by creating a new blank document in Illustrator and then creating point text and area text objects that match the type style and size settings in the Corel-generated document. I'll copy those new text objects into the Corel-generated document and use the eyedropper tool to copy the properties of the corrected text objects to the ones that aren't spaced correctly.
