Resolved Can't download anything from the MAS

I was seeing a blank update window, very odd.

Security Update 2020-07 seems to have resolved it.

Just now 4 updates installed without a hitch. Time will tell.

Do you have Safari icons blank? and Open With (Info on the link icon) greyed out?

Anyway if you double click to update any app it will download the update.
Just discovered by chance and didn't update to the latest security update

In my situation the Mac App Store badge and menu showed I had 4 updates, but the Updates tab was completely empty - totally white.
