GuzzleHttp\Psr new version having some minor bug. So update below file manually
vendor\intervention\image\src\Intervention\Image\Commands\StreamCommand.php
$this->setOutput(\GuzzleHttp\Psr7\stream_for(
$image->encode($format, $quality)->getEncoded()
));
Updated this like
$this->setOutput(\GuzzleHttp\Psr7\Utils::streamFor(
$image->encode($format, $quality)->getEncoded()
));
Note: This is not permanent solution untill GuzzleHttp\Psr fix in new version
