Unable to change the default Stock library

Unable to change the default Stock Library. If I try saving the image again, the Library disappears. Also, if I select "My Library," it doesn't load and the screen just turns white (blank). If I refresh, it goes back to the home screen. Going to https://assets.adobe.com/libraries only allows you to view the libraries; not select a new default Library.

I've done multiple things to no avail:

• Refreshed my screen
• Logged out and logged back in
• Tried both Chrome and Safari
• Completely rebooted my laptop

Please let me know if there is a resolution I'm unaware of or if Adobe realizes this is an existing problem that started about 2 months ago.
