When I click the Design > Pages , the page is redirected to this url:

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..
