Which usually happens if there is a problem with the Avisynth or Vapoursynth script used.
Looking at the Vapoursynth script used:

I don't see any issue with the script. => Does the Vapoursynth Preview work, or does it show an error?

DGindexNV can parse the files without any problem and also extracting the audio tracks.

Okay, since you didn't tell Hybrid to use DGDecNV, it is not using it, but normal DGIndex&DGDecode.
You can tell Hybrid to use DGDecNV, by enabling "Filtering->Vapoursynth->Misc->Source->Use DGDeNV when available".
