Errors running the Remix example on Windows OS

[Ryan Woodcox]

Describe the bug

Running the Remix example on the Windows OS returns the error: [vite] Internal server error: No CSS for file: /app/components/HelloWorld.css.ts

1. Install the latest remix, vanilla-extract and vite dependencies into the Remix example
   npm i @remix-run/node@latest @remix-run/react@latest @remix-run/serve@latest @vanilla-extract/css@latest
npm i -D @remix-run/dev@latest @vanilla-extract/vite-plugin vite@latest

2. Install the missing lightningcss dev dependency for the Remix example:
   npm i -D lightningcss

3. Run the example npm run dev

4. Recieve the error: [vite] Internal server error: No CSS for file: /app/components/HelloWorld.css.ts

5. A workaround to run this example on Windows OS is to downgrade the @vanilla-extract/vite-plugin package to version 3.9.5
npm i -D @vanilla-extract/vite-plugin@3.9.5

6. The example works on Mac OS without having to downgrade the @vanilla-extract/vite-plugin package to version 3.9.5

After a very brief investigation, I can confirm that the issue is only present on Windows.
Compared to Linux, the exact same file is being loaded, namely /app/components/HelloWorld.css.ts, yet there is no CSS found on Windows.
