Error during project creation

Sorry but I needed an answer. And I finally got my answer on my own.

version lts v18.20.3 doesn’t work, nor v20

this command doesn’t work npx create-strapi-app@latest my-project --quickstart

If you remove the qucikstart and configure à la mano, it works, why ???

The tool worked great 1 year ago and now it’s impossible to install, the commands in the doc don’t work.

The video tutorial dates from v3, but we’re about to upgrade to v5, so why the delay ???

the ia bot indicates a v14 or v16 version when the doc indicates something else, why ???

I need answers to my questions, hence the ping, because otherwise I wouldn’t have gotten any answers.
