I think I reproduce this issue:

If I define a vue.config.js (even with just a baseUrl config), then the files are directly in the dist folder, instead of in dist/js and dist/css:

  dist/chunk-vendors.d99df5b7.js     1103.67 kb          344.56 kb
  dist/app.39f1f482.js               11.36 kb            4.65 kb
  dist/chunk-vendors.b8827354.css    277.19 kb           32.52 kb
  dist/app.7335e73a.css              0.07 kb             0.09 kb

looks like issue is coming from this code:
