"bad sequence header magic." usally means there is a problem with the Avisynth or Vapoursynth script.
Looking at the Vapoursynth script in the debug output:

I don't see anything wrong with it.
-> Try whether Vapoursynth Preview porperly shows a preview or whether it reports an error message.

Ps.: If you installed the latest version over an existing install which was 2021.07.18.1 or older, make sure to deinstall the previous installation, otherwise Vapoursynth will fail.
PPs.: The video download link doesn't work, asks for a username and password.
