Why headers are empty for new response ?
Real code example, is that I am using redirect() helper inside method login() and it is not works because new response headers are empty for some reason.
"slim/slim": "^4.8.1",
"slim/psr7": "^1.4",
function redirect(string $routeName, array $data = [], array $queryParams = []): Response
{
$response = new Response();
$response->withHeader('Location', urlFor($routeName, $data, $queryParams));
return $response;
}

function redirect(string $routeName, array $data = [], array $queryParams = []): Response
{
$response = new Response();
$response->withHeader('Location', urlFor($routeName, $data, $queryParams));
$response->getBody()->write("Hello");
return $response;
}
Added for test and it works
$response->getBody()->write("Hello");
but $response->withHeader is not.

The headers are immutable. This should work:
$response = $response->withHeader('Location', 'new url');

Thanks! it is works
but does this correct here:
/**
* {@inheritdoc}
*/
public function redirect(string $from, $to, int $status = 302): RouteInterface
{
$responseFactory = $this->responseFactory;
$handler = function () use ($to, $status, $responseFactory) {
$response = $responseFactory->createResponse($status);
return $response->withHeader('Location', (string) $to);
};
return $this->get($from, $handler);
}
}

Yes this is also correct in this context. It just returns the new instance directly.
