CC Libraries panel is blank in all Adobe Apps

I'm on a Macbook Pro, Mojave OS (my company will not let us update to Catalina yet). All of my Adobe CC apps are up-to-date.

My Libraries panel in Illustrator is blank. In InDesign and PhotoShop, if I click the Libraries panel from the Window menu, it opens for a fraction of a second and closes again. 

I have tried: 

• Deleting the CC Libraries cache from ~/Library/Application Support/Adobe/
• Running the Creative Cloud Cleaner tool 
• Installing the latest Creative Cloud Libraries manually 

None of that has worked.
