Sorry, to say this but the debug output is useless.
Create one where you use Vapoursynth and another one where you use Avisynth, not one where the processing is mixed.
Currently I can see that the processing of the Avisynth script aborts due to some problem with the script, but I instead of the Avisynth script the Vapoursynth script is only shown.
Also check if the Vapoursynth Preview works or whether it alreads shows an error.
My guess atm. is that the source filter has a problem with the input.

Ps.: As a side note: I would recommend to either use some HDR to SDR conversion or also signal the HDR info in the output.
