Just installed the project, using opencode+gemini-3-fast-preview model to run the initial commands

Got same issue, in my case root cause is tailwindcss tries to scan & follow symlink i created (external locations) and Turbopack's filesystem resolver panics because the resolved path leaves its root boundary.

The error surfaces during CSS processing (PostCssTransformedAsset → evaluate_webpack_loader) but the actual trigger is Tailwind's content scanning traversing the symlink.

Solution

Disable Tailwind v4 auto-content detection and explicitly list code directories.

/* After — only scans listed directories */
@import "tailwindcss" source(none);

@source "../app";
@source "../components";
@source "../hooks";
@source "../lib";

Great! It will be helpful next time, I opted for webpack instead, it worked normally. Seems like the error was just with turbopack.
