I see the same error messages in log as for Voyo Serbia :
[Info]: [DC.Base] "GetMaskMatchedVideoStream mask: Mask_video_codec"
[Info]: [DC.Base] "m_selectDownloadVideoData eVideoCodec: unknown"
[Critical]: [DC.Base] GetCloserTrackByLowwerBoundResolutionAndBitrate w/h empty.
[Info]: [DC.CommonDL] **** Parse M3U8 download data fail.
So it looks like SF v7 have a problem with some unprotected m3u8 files ..
.. however, SF 6267 + 6262 cannot start the DL either:

Since I can’t change SF’s behavior, all I can do is refer you to yt-dlp:
