I am trying to change some users’ access to various menus in my store for which I’m the store owner.

ADMINISTRATION > [Select Store] > Store access/Manage access

I get an error saying that “There was a problem loading this page”.

Refreshing the page sends me to a 404/The page you’re looking for couldn’t be found.
