To add: this happens within the Creative Cloud App.
Sorry for the delay in response. The team is still investigating on this long time issue where fonts are taking long time to load. We would request you to please share the requested logs here: https://community.adobe.com/t5/adobe-fonts/fonts-takes-too-long-time-to-get-installed/m-p/11927267#M... with us so that we can share them with our dev team for investigation.
We will try our best to help.
