Bug Unity 2019.4.18f1 - Package Manager Blank (But Successfully Loaded)

Unity 2019.4.18f1 Personal <DX11>

EDIT: The same is happening with the UIElements Debugger window. Attached an image to show that as well.

The Package Manager, when launched, is completely blank. However, when hovering your mouse around the package menu, there are clickable items and expandable fields as you can tell by how the mouse changes (however, as previously stated, it appears completely blank unless hovering in specific areas of the window).

Steps I tried to fix the issue:

• Create brand new project (issue is happening in every project I have).
• Restart Unity & Unity Hub
  
• Re-import assets
• Reset Packages to Defaults

Something else to note is that these are all Universal Render Pipeline projects. I have not tried other types of projects, however I don't suspect that's the cause.

Displayed below is the console log, followed by pictures of the project.
(if the image doesn't show, I also uploaded it directly here. Seems this forum dislikes imgur links)

I am having the same problem on this update.

Some packages such as Sprite Editor are also missing some functionality.

Hope this is also the case for you.
