Comment:

 @stentibbing thank you for the ticket and welcome to Trac!!

 I can confirm that `get_page_by_title( null )` in 6.1 indeed returns a
 `WP_Post` and that it did not in WP 6.0.x.

 This bug was introduced in [54234].

 @spacedmonkey I think to easiest fix would be to check whether
 `$page_title` is empty because constructing the `WP_Query` and calling
 `_doing_it_wrong()` if it is and returning `null` in that case.
 Thoughts?
