Bloomberg recipe failed / Only fetching index and summary (Calibre 9.13.0)

[yhjm]

Hi everyone,
I've been using Calibre's built-in recipe to download Bloomberg news for a long time, but it recently stopped working properly. I do not have an official paid Bloomberg subscription, and the recipe used to fetch free content perfectly.
Now, when I run the recipe, it successfully bypasses the initial wall, spoofs the User-Agent, and parses the feed index along with article summaries (e.g., Markets, Technology sections). It even completes the process and outputs an EPUB file. However, the final EPUB file is essentially an "empty shell"—it only contains the cover, the Table of Contents, and article summaries, but no actual article body/text.
It seems Bloomberg might have implemented a strict hard paywall or updated their anti-scraping/bot-detection measures recently (similar to the recent changes made by The Economist).
I am currently running Calibre version 9.13.0 on Windows.
Here is the complete detailed log from my Calibre fetch status:
