Debugger does not work on Windows

[ShortRoundDev]

In the documentation for the VSCode extension, it says:

Navigate to the built OCaml bytecode executable in VS Code Explorer panel (a .bc file in _build directory), right click on it and select "Start OCaml Debugging (experimental)".

The debugger launches immediately.

On Windows 11, it runs the following command in the powershell terminal:

c:; cd 'c:\Users\[name]\source\repos\shortrounddev\Haruko\_build\default\bin'; ${env:CAML_DEBUG_SOCKET}='127.0.0.1:56183'; & 'c:\Users\[name]\source\repos\shortrounddev\Haruko\_build\default\bin\main.bc'

Which seems to launch a detached debugger client but no debugger (I suspect because trying to run a .bc file directly with no program associated does nothing).

Additionally, the generated launch.json file similarly does nothing:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "OCaml earlybird (experimental)",
            "type": "ocaml.earlybird",
            "request": "launch",
            "program": "${command:AskProgram}",
            "stopOnEntry": true
        }
    ]
}

Pops up an info box in the bottom right which says:

File system provider for c:%5CUsers%5C[name]%5Csource%5Crepos%5Cshortrounddev%5CHaruko is not available.

Are there up to date instructions for how to launch the debugger?
