The panels in the user interface for both Illustrator and Photoshop have started not rendering properly (aka disappearing) both for the document panel and for workspace panels the ever since upgrading to Catalina on Mac. This most commonly happens when pressing "F" to switch between document views. Other times when switching from another application to the Illustrator or Photoshop window, the entire document disappears despite the Window dropdown menu saying it is open.

I have contacted Adobe Customer Support and they have continually told me to delete my preference files (Illustrator) or turn on/off Legacy compositing (Photoshop). Despite doing these, neither has fixed the problem. How can this be solved for good? It's highly disruptive to my workflow.
