I updated to the latest version of Illustrator (24.3) and opened a document I had created in a previous version. Most of my text was missing. I checked and the font was still available and activated. I deactivated and reactivated and that didn't help. When I click the text, it gives me the message that "This text was created in a different version of Illustrator. Editing the text may cause some changes to your text layout. Basic formatting will not be affected. Do you want to continue?" The font is PeachyKeenJF. Only a few letters/numbers actually show up. I'm on Windows 365.
