Hello,
The issue might not be related to the 'Navigation module', but perhaps related to the point mentioned in https://www.drupal.org/project/menu_item_role_access/issues/3270866 🐛 change of user role has no effect on menu items access without a cache purge Needs review comments #4 and #7
'The check is never performed for any menu item with an internal route, unless you have configured to Overwrite the default access check' in the module configuration in /admin/config/menu-item-role-access
rmasoad@gmail.com , can you try enabling this option and see if it solves the problem for you?
