Deoldify Vapoursynth filter

[Akila]

I uninstalled Python and all what I installed flowed by (https://github.com/dan64/vs-deoldify/) as it was in the thread so I believed I was supposed to follow the instructions.
I uninstalled Hybrid, reinstalled Vanilla Hybrid, extracted "VapoursynthR65_torch_2024.05.11.7z" and I think it is working now.
But only if I select "Custom" -> DeOldify Only". the default presets like "Fast", etc. that are "Simple" (Color Method) I get an empty video file of 500kb, blank picture.

Preview gives me no error (using Simple /or DDcolor): just blank screen / picture
