Please call composer update and try again. Make sure you have 3.1.1

I'm having an error with 3.1.1 on an app that was working right with 3.1
When calling
@widget(\Namespace\ClassName::class, $options]
rendered correctly as
<?php echo Theme::widget('\Namespace\ClassName', $options])->render(); ?>
the system says that the class does not exists appending App\Widgets\\Namespace\ClassName

Where did the App\Widgets\\ comes? I'm not using namespaces placeholders or nothing.

Any help will be appreciated. Thanks.
