Comment (by merlinxvqzy1):

 Are you encountering an issue where deleting a category results in all
 posts under it being assigned the default category? A better approach
 would involve checking if posts have been assigned another category before
 applying the default category. Additionally, there is a bug where if a
 post was assigned both the deleted category and the default category, the
 default category will be assigned again, resulting in duplicate entries in
 the wp_post2cat table. Implementing a check to avoid assigning the default
 category in such cases would prevent this issue.
