I noticed the same. I wanted a simple crud webapp and suggested an insane techstack involving C#, Razor Pages, MSSQL and more. I went with my planned setup of python flask with an sqlite db which served me well for years.
It's still incredibly important to have a human in the loop correcting design decisions and having good taste.
Was your prompt just "I want a simple crud webapp" and that's the extent of it? There's absolutely no way you included the words "python", "flask", or "sqlite" and it still went with a Microsoft stack.
