If anyone else is having this problem, it had to do with using Duplicator to move from Apache to nginx. I installed Apache and am using that instead, it works just fine now.
I am getting some 404 errors looking for http:/localhost/wordpress/wp-json/elementor/v1/globals. No wp-json folder exists, should there be one?
I used the method described here for the error message, but Elementor still will not start.
