Error when opening link to page already defined in Pages

So I’m having an issue with trying to open one of the pages I have created. It is made in pages and is clickable in the Navigation section, however I am unable to view the page whenever I click on the link to that page specifically. The link is not broken, and upon inspecting the element in Google Chrome I am getting a 500 error code.

I don’t know what to do in this scenario, how would I approach debugging this case?
