Very Dark Black Screen Issue After Logging into BIG-IP Web GUI

Hi everyone,

Very Dark Black screen appears when I try to access the BIG-IP Web GUI. The login page loads fine, but after logging in, the screen stays blank, and no interface elements are displayed. I have tried using different browsers and cleared the cache, but the issue persists.

Has anyone experienced this or knows how to resolve it? Any help would be greatly appreciated. Thank you!
