When changing the background color of the ProgressBar, using the UI Toolkit debugger, you can see that the color has been updated. It doesn't show up in the Viewport of the UI Builder because the ProgressBar has a child that acts as the background. So to change the background color of the ProgressBar, you will need to create a selector targeting the .unity-progress-bar__background uss class instead.

Reproduction steps:
1. Create a new project
2. Create UI Document (Create > UI Toolkit > UI Document)
3. Double-click on newly created Asset to open UI Builder
4. Drag and drop Progress Bar Element to Hierarchy
5. Change the background color of the Progress Bar in the Inspector
6. Observe the Progress Bar in the viewport

Actual result: Background color does not change in the viewport
Expected result: Background color updates and displays correctly in the viewport
