Map Not Working – Page Not Found

I have been using Maps Builder for the better part of 2 years, I add pins for each hike that I do. Suddenly, over the weekend, the page stopped displaying on the public side. I am also not able to add pins on the map. This is extremely frustrating since this page hosts over 80 pins that are manually added. Happy to provide more information, but looking to resolve this problem. From a site perspective, I have not updated the theme or any major parts of the site. I have had a similar issue in the past and was forced to recreate the map from scratch, do not want to have to do that again.

Thank you in advance.
