I'm using Illustrator 24.1.2 with a creative cloud student subscription on Mac OS Catalina. When I try to activate any font not installed locally, the activation process will go on for five minutes, then terminate itself. No font would be installed. I Googled around for similar problems, and many suggested looking at the "Font" tab of the creative cloud app. I don't have that tab. The only tab in my creative cloud app is "Apps".
