[Bug]: Storybook initialization hangs on loading screen with Next.js v15.3.2, Vitest, and styled-jsx module export error

[satoukouga]

Describe the bug

When initializing Storybook in a Next.js v15.3.2 project using Vitest, the Storybook UI gets stuck on the loading screen and does not display component information. In the browser console, I see the following error:
Uncaught SyntaxError: The requested module '/node_modules/.pnpm/[email protected]_@[email protected][email protected]/node_modules/styled-jsx/index.js?v=1422bc3a' does not provide an export named 'StyleRegistry'

Reproduction link

Reproduction steps

1. Create a new Next.js project using pnpm dlx create-next-app@latest(15.3.2).
2. Install Storybook by running pnpm create storybook@next(9.0.0-rc.4).
3. Initialize Storybook as prompted.
4. Start Storybook using pnpm storybook dev -p 6006.
5. The Storybook UI remains on the loading screen and does not display component information.
6. Check the browser console for the error:
   Uncaught SyntaxError: The requested module '/node_modules/.pnpm/[email protected]_@[email protected][email protected]/node_modules/styled-jsx/index.js?v=1422bc3a' does not provide an export named 'StyleRegistry'

I'm encountering the same issue in a Turborepo monorepo setup, also using pnpm (v10.11.0). However, adding styled-jsx as a direct dependency seems to have fixed the issue for me.

I have re-installed with just the minimal setup and it worked.
