Please give us a description of what happened.

I have registered custom post type / custom taxonomy and I changed the permalinks by 'pre_get_posts', 'parse_request' and 'request', 'post_type_link' and 'term_link' hooks.

I get a Uncaught TypeError: "Cannot read property 'split' of null" in wp-seo-modal-800.min.js?ver=8.0:6, when edit posts (posts and custom post) and categories (regular and custom taxonomies).

No error without YOAST and with / without other plugins.

Technical info

WordPress: 4.9.8
Genesis: 2.6.1
YOAST: 8.0.0
PHP: 7.2

Yes, I understand your problem with over 1000 unresolved issues.

I solved my problem now. Was a issue with the 'locale' filter.
