Font Favorites missing after Illustrator upgrade

Hello @Helen36086108x6ey,

Thanks for reaching out. Would you mind checking if the preferences ("Adobe Illustrator Prefs" file) from the previous version of Illustrator are still saved?

For macOS

• ~/Library/Preferences/Adobe Illustrator 27 Settings/en_US*/Adobe Illustrator Prefs

Note: Location starting with this "~" sign indicates the User Library, which is hidden. So, you need to copy & paste the exact path in spotlight search or from Finder Menu > Go > Go to Folder > Paste the location in the dialog box like this:

For Windows

- Go to Location C:\Users\%USERPROFILE%\AppData\Roaming\Adobe\Adobe Illustrator 27 Settings\en_US\x64

If yes, open the file in Notepad, copy the following lines from it, paste them into the Illustrator 28 preferences ("Adobe Illustrator Prefs" file), and relaunch Illustrator to check if it helps:
