I've given up hope that something that used to work will be fixed.

I don't want to get your hopes too high but the latest yt-dlp just listed a fix for the bibeltv extractor in their nightly release Changelog. That should mean that sometime down the road when StreamFab uses the stable version of that release it appears that you should be able to get at least some of your shows. Since the yt-dlp Changelog didn't mention anything about DRM maybe the StreamFab problem wasn't a DRM problem after all. I don't know. I haven't spent even 2 seconds looking at the bibeltv.de website. It appears that you were the one that brought up the possibility that it was a DRM issue in another message thread here on the Forum. It may not be and that would be to your advantage.
As far as I can see, StreamFab does not use nightly builds of yt-dlp so you'll have to wait until it is released on a stable build before you can test it out. Please don't bother Mona and the staff about it as it is out of their hands. It gets released when yt-dlp decides to release it.
