Copy/Paste Bug — Old Text Keeps Reappearing When Pasting from Point Text to Area Text

Hi all,
I’m running into a really frustrating issue in Illustrator and hoping someone can help or confirm if this is a bug.

Whenever I copy text from a Point Type object and paste it into an Area Type text box, Illustrator pastes the correct text but also includes a chunk of old text from something I copied dozens of attempts ago. This old text repeats infinitely inside the Area Type box. It just keeps duplicating itself over and over, flooding the box.

Here’s what I’ve tried so far (none of these have worked):

• Restarting Illustrator and my computer

• Creating a brand new file

• Pasting into a plain text editor first (like Notepad or TextEdit) to strip formatting

• Using Cmd/Ctrl + Shift + V to paste in place

• Clearing out overset text and checking for threading

• Manually clearing windows clipboard

• Uninstalling and reinstalling Illustrator

Despite all that, the moment I paste into an Area Type box, that old text comes back. It doesn’t happen when pasting into a Point Type box, only Area Type.

Has anyone experienced this? Is there a deeper cache I can clear, or is this a known bug?

Thanks in advance!
