            $output->writeln("Hi Customer");

Answer 1

"There are no commands defined in the "cache" namespace."

This makes me think the issue is above your CLI command.

Make sure magento command are properly installed do bin/magento list in the first place and see if the command doesn't fail, if cache:clean is available and if your new command is available too.My guess is that one of these steps will fail.

May be you will be provided more information from var/log/exception.log and/or var/log/system.log

<?php

namespace Vendor\Module\Console;


use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use \Vendor\Module\Helper\Data;

class Hicustomer extends Command
{
   
    
    public function __construct(Data $helper)
    {
            $this->helper = $helper;
            parent::__construct();
    }
    
    protected function configure()
    {
        $this->setName('cloudways:hicustomer');
        $this->setDescription('Demo command line');
        parent::configure();
    }

    protected function execute(InputInterface $input, OutputInterface $output)
    {
       
        $this->helper->checkImage();
      
        $output->writeln("Hi Customer");
    }
}
