@aralroca Have you tried deleting the .next directory and running npm run dev again?

i have similar error, but cannot find ./next/build-manifest.json for mine (just cache/ and server/ folders are created in .next/, no static/ or jsons) trying to reproduce on minimal repo but no luck so far, did anyone find workaround for this?
