Slim corrupting file on download

1

I’m having trouble downloading a file through slim, in the images below, the file on the left the original .tmp file on the server and on the right the file after down using the class below.
Regardless of the class if I put a txt content to download the same problem also occurs, it seems that it puts an empty space at the beginning of the file and removes the last character.
The strange thing and that this happens in some servers and others not, windows servers with Apache 2.4.47 Handler + PHP 7.3.28

<?php
$response->getBody()->write($nfse->xml);
            return $response->withHeader('Content-Type', 'application/xml')
                ->withHeader('Content-Disposition', 'attachment;filename="' . $nfse->name . '.xml"');

This can happen when you have a PHP file somewhere with a php end tag like ?>

I searched for files of this type too I didn’t find it, the project on both servers are identified, I managed to get around with ob_start, but I would like to find the problem

 public static function getResponse(Response $response, $file, $outputName = null): Response
    {
        @ob_start(null);
        @ob_end_clean();
        @ob_clean();

        if (is_string($file)) {
            $stream = new Stream($file, 'rb');
        }  else {
            $stream = $file;
        }
