Fresh Sage install and Bootstrap is not loading up

So I did the normal install composer install -> /vendor/bin sage meta, config, preset (I am using windows so that’s why I had to execute those)… but then when loading the new site, II still don’t see any bootstrap loading up. I tried adding a '<h1 class="display-1" >' on the 404 page to see if it loaded bootstrap but it didn’ the main.css file is completely empty. Any idea why could this be happening?
