 After installing WordPress 7, the admin area becomes unusable for post
 management.

 Steps to reproduce:

 Install WordPress 7
 Log into the WordPress admin dashboard
 Go to Posts → All Posts or Posts → Add New

 Observed result:

 The page becomes completely blank (white screen). No content is loaded and
 the editor does not appear.

 Expected result:

 The post list and the editor should load normally without errors.

 Environment:

 WordPress: 7
 PHP: 8.3.23
 Server: Apache 2.4.67
 Theme: Hestia 3.3.3
 Active plugins:
 Orbit Fox Companion
 Rank Math SEO
 Site Kit by Google
 WP-Optimize
 ManageWP
 WP File Manager
 Other plugins attached in the system report

 Additional information:

 The issue disappears after downgrading back to WordPress 6.9.4. Without
 the downgrade, all sites become unusable due to this problem.
