Attempting a Windows Service

On my Mac, I wrote a small nagger app to help remind me when I may have extended a break too long.
It is connected via mqtt to a hardware bell I have on my desk.

Recently I have been spending a bit too much time in Factorio so wanted to see if I could make a similar version on Windows.

I have not previously used my Windows PC for development (I do all of my work on MacOS or Linux), so the first step was to install VSCode, uv, and git.
This was not particularly difficult and recently it seems like installers automatically handled updating PATH for powershell.

I quickly got a script working using MQTT for some things, and it worked fine when being directly called.
The next step is to get it running as a Windows service.
While I found some guides and stack overflow posts, this is where I am currently paused.

Error starting service: The service did not respond to the start or control request in a timely fashion.

If I was on MacOS or Linux (Systemd) I know more about how to debug a running process, but I'm fairly new to this on Windows.
Using Event Viewer and other tools, I try to look up the reasons but it is somewhat difficult to use and does not seem to provide detailed information.

It's possible that I will need to try something like PyInstaller to package it up differently.

For now I am just using task scheduler to run the task at login, but ideally I would get it working as a proper service at somepoint.

This small excercise has not exactly endeared me to Windows development, but it is also a reminder of how used we get to our native development platforms and how foreign a different platform can feel, even if the underlying programming language is the same.
