Page Redirected to controller=AdminDashboard

[Hessam]

When I click the Design > Pages , the page is redirected to this url:
https://mydomain.com/xxx/index.php/improve/design/cms-pages/index.php?controller=AdminDashboard&token=dbd75324ee2de9a115ee83ec8797709d

We have upgraded website from 1.7.5.2 to .1.7.6.3 as well.

Also I attempted to solve the issue with these steps:

• clearing cache in BO
• deleting var/cache/prod and dev
• regenerated the .htaccess file through toggling the friendly URL config
• also checked for any class that overrides something.. and disabled all of them
• disabled all non-presta modules
• composer dump

but not happened

I figured out that this is one of the classes which are migrated to symfony controllers..
