Unable to Access Material Library in 3DEXPERIENCE (Fluid Scenario Creation)

Hi,
I am facing an issue with accessing the Material Library. 
Issue Description:

  • I was able to access and assign materials from the Material Library successfully.
  • However, within the same session (approximately 10-15 minutes later), the Material Library became inaccessible.
  • Currently, when attempting to apply material, the library is not loading / appears empty / not accessible (please adjust based on your exact observation).

Steps Already Tried:

  • Cleared local search cache and refreshed session.
  • Restarted the simulation app
  • Verified login session
  • Checked internet connectivity

Request you to kindly have a look and provide a resolution
