I have Windows 7, 64bit, running Illustrator CC and all of a sudden today I am not able to use the text tool and when I try to use the select tool on certain areas of the file the error message comes up that I attached to this.
Same here, Autumn 2021…
Mac OS X All Up to date.
The same error when trying to draw with Pencil in track editing mode.

Is this specific to one particular document? Or in any, even a new, document?
If the latter, would you try trashing the AI preferences?
