blog index page come up white blank page – rest of site fine?

here is the address: https://www.angiestrauss.com/wordpress

then click on ‘blog’ button in the nav (that’s the page I’ve assigned to the WP blog index.

It was appearing perfectly – I can’t figure what happened – anyone have any idea what file this might be? I have disabled all of my plugins and still no difference

Thanks sincerely !!!!
