To Reproduce

1. Create Next.js config with the following:

module.exports = {
  reactStrictMode: true,
  swcMinify: false,
  webpack: (config) => {
    config.devtool = 'source-map';
    return config;
  },
};

2. Run yarn build
3. Examine the build being stuck on "Creating an optimized production build ..."

Side note: We noticed this because a lot of users were reporting that their app doesn't build anymore with @sentry/nextjs installed. Some more info with useful reports in this issue: getsentry/sentry-javascript#6782 (comment)
