Description

From a list of videos, 1 video failed to download a thumbnail, although Youtube is showing one and I see one in the browser (namely, https://i.ytimg.com/vi/VXhmeGZHRp8/hqdefault.jpg, https://i.ytimg.com/vi/VXhmeGZHRp8/maxresdefault.jpg). See verbose output above.

Related, yes, but nothing more. That PR is not merged yet, and converts webp files after download to jpg files with --embed-thumbnail. This is not the case here, the thumbnail is not even downloaded correctly.
