Page with large table doesn't load

I have an appendix in my guide, which is one very long table. It is definitely published and it appears in the TOC on the side. But when I try to open it from another page in my project, the icon on the browser tab spins as if it's thinking, but then even though the URL changes to the correct URL, I still see the same page I was on before.

If I try to open the page directly from the URL (not from another page in my project), I get a 500 Internal Server Error.

Why is this happening and how can I fix it? Thanks.
