I have a large code base with many components and over 50 routes when our team switches to next js. Our programming experience became awful and after every update The next.js is worse than the previous version, I don’t know what to do to fix it.

I tried so many ways like change static import to dynamic import remove any index.ts file and change all infrastructure of projects and add & remove so many configs in next.config.js i dont know What should i do to fix it i gonna so happy if you to share your experience to me
