 Hi there,

 I believe this maybe a bug or at least an unchecked condition (post/page
 does not exist) throwing the above error. I have legit crawlers visiting
 that cause these errors.

 Running 5.3.2. All plugins disabled (except for Health Check &
 Troubleshooting). Theme: Twenty.

 How to re-produce : https://your.site.com/news2020/feed/atom/

 It is key that the slug for the post/page does NOT (NO longer) exists.

 Stack trace:

 A variant (same sort of problem) throws an error in class-wp-query.php
 with the following:
