Get stuck when using magento2/vuestorefront/composer

rookie here.
Im trying to connect magento2 with vuestorefront using composer. I am following this guide: https://docs.vuestorefront.io/magento/installation-setup/configure-magento.html.

On step 2, after using this command: curl -s https://raw.githubusercontent.com/markshust/docker-magento/master/lib/onelinesetup | bash -s — magento.test 2.4.4.

Docker fires up as it should and Composer asks for authentication like so:

Composer authentication required (repo.magento.com public and private keys):
Username:

Here, i pasted my public key (enabled) but cannot go to the next step. When I cancel the terminal(ctrl+c) I get this message:

‘***08c7’ is not recognized as an internal or external command,
operable program or batch file.

has anybody else got this problem and know a way to solve it? Thanks!
