All images in the background selection in the graphics panel do not load for viewing or use

I am using MacOS Catalina and Photoshop Elements 21. I cannot get the remainder of the images under "backgrounds" in the graphics panel to show. When I click on it to try to use it anyway since it will give the name of the item, I get a window that says the server must be busy but this has gone on since I purchased Elements 20 and 21. I am connected to the internet. It doesn't matter the time of day, I get the same results.
