Answer 1

É uma pena que você tenha deixado de fora o caminho - provavelmente é o culpado.

Esta mensagem de erro indica que o npm não tem permissões para executar alguma operação de arquivo:

npm ERR! Please try running this command again as root/Administrator.

Isso pode acontecer ao executar npm install -g <something> (instalando algo globalmente), mas para instalações locais geralmente indica seu erro no caminho.

E, de fato, o caminho da segunda linha parece negativo:

Creating a new React app in C:\Users\Desktop\my-react-app.

Seu nome de usuário está faltando! C:\Users contém perfis de usuários, que contêm Desktop pastas. Portanto, o caminho deve ser C:\Users\ YourUsername \Desktop\my-react-app .
