已解决@ngtools/webpack多包安装错误，但升级后遇新问题

Hey there! Glad to hear you worked through the Error: several @ngtools/webpack packages installed issue by upgrading to the 1.7.0.beta.1 version. Now that you're hitting a new snag, let's figure this out together.

To help diagnose the problem quickly, could you share these key details?

• The full, exact error message you're seeing (including any stack trace that comes with it)
• Your current Angular core/Angular CLI version
• The webpack version listed in your project's package.json
• Any recent tweaks you made to configuration files (like angular.json, webpack.config.js, or tsconfig files)
• A quick snippet from your package.json showing the @ngtools/webpack entry plus related Angular and webpack dependencies

Once you share these, we can narrow down if this is a compatibility mismatch, a configuration oversight, or a known quirk in the beta release.
