I've reviewed your profile & it looks alright. Have you tried changing the internet network?
You've tagged Windows, so try these steps:
- In the Creative Cloud app, press CTRL + ALT + T (Win) or CMD + OPT + T (macOS) to launch Creative Cloud Troubleshooter & select 'Close Creative Cloud and related processes' > click on Go.
- Go to Task Manager & force stop any other Adobe-related processes & the process called 'Adobe IPC Broker' has to be closed after all the other tasks are closed.
- Windows - Press Windows + R to open Run Dialogue > enter %TEMP% > Click on OK.

- Delete any files or folders with 'NGL' in their names.
- Restart the computer
- Sign in to Creative Cloud again and let me know if the issue exists.
Thanks!
