[Windows] Can't build the docs on Windows

[UltraInstinct05]

Problem Description

Currently, it seems that the docs can be built only on Linux & MacOS but not on Windows.

Steps to reproduce

1. Clone the repository & initialize the submodules.
2. Run npm install
3. Run npm run start-docs

Expected behavior

The docs should build & the stdout should show that the static files are being served on port 3000.

Actual behavior

The docs are built but the express server doesn't serve them on 3000.

Additional Information

OS Platform & Version: Windows 10, Version 10.0.18363, Build 18363
