If I remove bootstrap no vendor.css is created

[Axi]

I've removed all dependencies of bootstrap.css because I don't want to use it:
from package.json
from webpack.config.vendor.js
did all from scratch after cloning repository.
Afterwards:
npm install
dotnet run
no vendor.css has been created in wwwroot/dist
Did I miss something?

Can you run npm run dev and see if that builds and runs everything for you?
That is what actually runs the webpack command, dotnet run might not be executing it for you.

Hope that helps!
