Class "App\Model\User" not found

[hamadfayyad]

Thank you for everything you do it's great work
The blog is working and the admin page is working,
most of the sections are working but I'm facing issue when I go to the role and contact-us section in admin panel ( localhost:8000/roles ) and (localhost:8000/admin/contact-us)

The operating system: windows 10
php : PHP 8.1.6
node : v16.17.0
npm : 8.15.0
