Home Icon on page manager UI

I clicked the Home Icon by accident and now my admin is busted. I get “page is not working error”. Cannot access anything now. What is that home icon anyway?

I see in the docs:
" Set a new home page
Use Home icon to assign new home page. A new home page will be named index.html."

So this should not break the admin.php

When in the root I try to access /admin.php and now I get an error:

This page isn’t working

URL is currently unable to handle this request.
HTTP ERROR 500

Okay I figured it out. index.html was deleted somehow. So once I add back index.html all works as normal.

I am glad you’ve figured it out.
