I was able to reproduce this on a fresh install of Arch running anipy-cli v.3.8.0. It seems to throw the same error whether or not -D or --ffmpeg are used, but only for the dub, sub works fine.

I thought it was odd that it would say index out of range, since there are clearly later episodes that are in range, but it looks like the index in question is for the array of available video streams for episode 8. The first attached log (...T21.43.22...) is using the default settings, the other I specified worst available video quality; both error out the same way, which suggests that the streams[] array is empty or nonexistent, since 'worst' prompts it to check the 0th array element.

Browsing directly to the episode's listing on allanime, it looks like there are no available video streams for the dub of episode 8 (everything else is there as expected), but there is a page for that episode. I assume anipy is checking for a listing on the site, not whether the actual streams exist, since in most cases there should be no listing if the episode is unavailable. Because of this, there's no check for whether streams[] actually has elements.
