Stylesheets/javascript files won't load locally

My site (live site: https://davidgs.com) doesn’t display properly when run locally.

It’s extremely odd, as the console says:

[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (http://localhost:1313/css/main.css, line 0)
[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (http://localhost:1313/js/popper.min.js, line 0)

If I open the developer tools, I see that some of the stylesheets are loaded, while others are not:
2023-10-03_14-48-21

But if I look at the source, they are all loaded in the same way:

But those 3 .css files just refuse to load and I cannot figure out why. The code is all at GitHub - davidgs/DavidgsWeb at ESPTLS (I’ve got it in a branch in hopes of not breaking my entire website until this is fixed).

Any help greatly appreciated. This is the second time now that my Hugo site has broken (I believe with an update of Hugo, but I can’t say for sure).

I cannot build your site:

git clone --recurse-submodules https://github.com/davidgs/DavidgsWeb
cd DavidgsWeb/
git checkout ESPTLS
npm ci
hugo
