Hey, I ran into the same issue recently.

In my case, it happened after upgrading Next.js and integrating Sentry.
The error Next.js package not found usually means Turbopack isn’t able to detect the next dependency correctly. I noticed the debug output says Next.js version: 0.0.0, which means it’s not resolving properly, probably due to a missing or broken link in node_modules.

A few things that helped me:

• I double-checked that next was properly listed in my package.json
• Deleted node_modules, .turbo, and lockfile, then ran a clean install
• Made sure Sentry wasn’t interfering with the build

Hope that helps! Let me know if you’re still stuck, happy to take a look at your setup.
