I received a notification today that a random font was activated while I was working in Photoshop. A few minutes later I received a notification that over 200 fonts were deactivated and over 300 new fonts were activated. Not sure if this is a bug or if it means I may have been hacked.
Welcome to the community! Could you please let us know the version of the Creative Cloud Desktop Application you're using? Also, if you’re using Adobe fonts in an older version of Creative Cloud or in a third-party app, you may notice that Creative Cloud periodically cleans up fonts you don’t appear to be using.
