I am trying to create laravel project on windows but this problem show to me and
I try update the composer. the php version is 8.0.6, the composer version is 2.0.14, the laravel version is 4.2.5,

Instead of laravel new your-project-name you should use composer create-project laravel/laravel your-project-name 4.2.*
