My home page on my Listing Pro site now only has a small pulsating blue circle. How can I fix this?

My Listing Pro site was working well, but when I opened the site recently, there was only a blank page with a very small, pulsating blue circle. I have no idea what this means, and how I can fix it. All the rest of the pages are ok.
Any help would be appreciated. Thank you.

It’s probably WordPress update causing the issues but you gotta find it by yourself ( or hire a freelancer ) as this is beyond of “help”, it’s “work” for someone else.

The blue circle was there before I updated to the latest version.
