@vip30 I had the same issue today and my fix was to explicitly add @babel/runtime as a dependency. This was not needed before Next.js 14.0.4, so it needs some investigating as to why this is now needed.

Edit: It seems this has started on v13.5.7-canary.9, last working version was v13.5.6 - https://github.com/vercel/next.js/compare/v13.5.6...v13.5.7-canary.9

I handled this issue by deleting babel.config.js (= compiling SWC). But I still don't know how handle this with babel.

I have tried @jpedroribeiro solution is working as expected and we need to use some of the babel plugin which swc is not supported so we can't use SWC for compiling
