Checkout Page Loads Without CSS Woocommerce

Hello there,

I am new to WordPress and WooCommerce, and I'm currently creating a custom WooCommerce theme. I am almost done with the theme, but I am encountering an issue on the cart and checkout pages. While the content on both pages is displaying correctly, it is not loading the CSS, so the layout appears broken.

Could you please guide me on why this might be happening and how I can ensure the proper styles are applied to these pages?
