A VirtualBox machine with the name 'homestead' already exists

I HAD PROBLEMS with Homestead/Laravel/Vagrant/LAMP in Windows 10, the problem was: after development rather than showing full local Laravel website, it was shown Laravel default web page… After trying some debugging — I decided to upgrade VirtualBox, Vagrant

and finally, got another error: … well, what to try?

PS D:\htdocs_xampp\Laravel\Homestead2020> vagrant up
Bringing machine ‘homestead’ up with ‘virtualbox’ provider…
==> homestead: Checking if box ‘laravel/homestead’ version ‘10.1.0’ is up to date…
A VirtualBox machine with the name ‘homestead’ already exists.
Please use another name or delete the machine with the existing
name, and try again.
