I recall trying your package out earlier, but I didn't report here (I don't recall why, probably because it was involved and my tests were incomplete). As of now, several updates of other packages later, monerod won't start. Here are some debugging attempts:

I could proceed debugging with suggestions from AI chatbots further, but before this, I though I'd better wait for your suggestions.
