Class not found Error after migration

After migration from ZF2 to laminas (MVC) we got a class not found error/warning and our application is not running.

Warning: Class ‘Laminas\View\HelperPluginManager’ not found in PATH/vendor/laminas/laminas-zendframework-bridge/src/Autoloader.php on line 116

Class HelperPluginManager exists in path vendor/laminas/laminas-view/src. The files in this folder and its subfolders are still in the Zend namespace. Is that correct?

Are there any ideas for a solution of this issue?

This looks like a bug: if it is possible to create a small reproducer, consider opening an issue on laminas/laminas-zendframework-bridge, so that someone can investigate it.

I suggest to migrate a ZF2 app to ZF3 app first, then to Laminas

I got the same error with migrating Zend 2 to Laminas, after the migrated I get the following error:

Class 'Laminas\View\HelperPluginManager' not found in vendor\laminas\laminas-zendframework-bridge\src\Autoloader.php Fatal error</b> : Cannot declare class Zend\View\HelperPluginManager, because the name is already in use

I check socurce code of laminas/laminas-view component and see that the namespace of this component is Zend.

Version of laminas/laminas-view is 2.3.
Please help me for resolve it.
