I tried migrating an existing Next.js 15 project to Next.js 16 and encountered an error during the build process:

Turbopack version: v16.0.0-canary.19
Next.js version: 16.0.0

Error message:

Dependency tracking is disabled so invalidation is not allowed at /Users/jj/dev/actions-runner/_work/next.js/next.js/turbopack/crates/turbo-tasks-backend/src/backend/mod.rs:1514:13

Apparently I've managed to figure out the root of the issue and fix it. It seems to be caused by non-script (ts/tsx) files stored within app directory. I used to keep some icon files there (e.g. apple-icon.png, favicon.ico etc.) and moving those to public has just resolved the build error. Please let me know if this was helpful for you.

UPD. I just figured out that the issue is directly caused by using files with the same name but different format (e.g. icon.png & icon.svg). If all the file names placed within app directory are unique, build passes correctly.

Resolved my build issues by using apple-icon.png, favicon.ico and icon.svg. I have just removed my icon.png file in app directory.

Thanks for the insight.

enstyled Oct 27, 2025

Thanks @samoyedisco! I had icon.svg and icon.ico, removing one fixed the build for me.

Confirming I'm experiencing the same on next 16.0.1, multiple platforms. Had several icon files, moved the extra icon files out, project then builds without crashing when there is only a single icon.png in app source.
