Comment:

 @SergeyBiryukov identified the exact path for this particular error, which
 is caused by `wp-admin/includes/misc.php` being loaded via
 `wp_add_privacy_policy_content()` when an rewrite flush is requested
 outside of the admin context. That combo leads to `save_mod_rewrite_rules`
 `function_exists` check to pass. That function assumes `wp-
 admin/includes/file.php` has been loaded, which isn't true in this case.

 Patch incoming.
