Current behavior 😯

Running vite preview on windows results in:

node:internal/modules/esm/load:195
    throw new ERR_UNSUPPORTED_ESM_URL_SCHEME(parsed, schemes);
          ^

Error [ERR_UNSUPPORTED_ESM_URL_SCHEME]: Only URLs with a scheme in: file, data, and node are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'c:'

 ELIFECYCLE  Command failed with exit code 1.

Does not happen on vite dev.
This seems like a windows only problem.

Expected behavior 🤔

No error should be present.

Steps to reproduce 🕹

Steps:

1. vite build
2. vite preview
3. load the site
4. check console (not the browser one)
