Magento – Magento 2 : crontab is not working

I am trying to implementing cron job for my module but getting error in CLI.

I am using windows operating system.

here is crontab.xml

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/crontab.xsd">
<group id="customdesignsubcategories_cron">
    <job name="uploadFile_deletion" instance="vender\module\Cron\UploadFileDeletion" method="execute">
        <schedule>1/2 * * * *</schedule>
    </job>
</group>

here is UploadFileDeletion.php

<?php
namespace vender\module\Cron

class UploadFileDeletion
{
protected $_logger;
public function __construct(\Psr\Log\LoggerInterface $logger) 
{
    $this->_logger = $logger;
}
public function execute()
{
    $this->_logger->debug('Cron run successfully');
    return $this;
}
}

following commands i fire in CLI

php bin/magento cron:run --group="customdesignsubcategories_cron"

Error =>
