The obsidian‑astro‑submodule gist basically uses git to mirror a folder from your vault into an Astro project's content folder. On Windows 11 with Obsidian 1.5.9 and Node 20 I've had better luck keeping a published folder in my vault, symlinking it into src/content of my Astro site, then running astro dev to preview new posts, so a quick test could be to create a scratch note called TestPost, symlink its folder into your project, run git add && astro build and see whether that gives you a working page; does that fit your tooling or do you need a plugin?
