Disable the terser plugin by editing the file:

node_modules/@angular-devkit/build-angular/src/angular-cli-files/models/webpack-configs/common.js

and comment out:

extraMinimizers.push(new TerserPlugin({
  sourceMap: scriptsSourceMap,
  parallel: true,
  cache: true,
  terserOptions,
}));

rebuild the app with ng build frontend --prod and you should be able to see in the console which service can't be injected.
