Typo3 Upgrade 9 to 10; ttnews with extender fails for new fields in frontend

I have updated from 9.5.0 to 10.36. Sofar the website and extensions are working fine.

tt_news is updated to 10.0.1 and extender to 7.1.0

On Typo 3 9 I had already created new fields using the extender.

After updating and installing the extensions, all the fields can be viewed in the backend but the values (of news fields) are not viewable in Frontend.

I get the following error for address.php

1/1) Symfony\Component\DependencyInjection\Exception\InvalidArgumentException
Expected to find class "Evoweb\Extender\Domain\Model\Address" in file 
while importing services from resource "../Classes/*", 

but it was not found! Check the namespace prefix used with the resource.

Could you please help me here.
