FIXED - Vapoursynth/SMDegrain fails

[vlada]

Whenever I try my favourite SMDegrain filter in Vapoursynth, it crashs. Currently I'm testing Hybrid 2023.03.17.1 (Win64). Even with latest smdegrain.py from github. The last version it worked was for me 2022.05.04.1. Doesn't matter video source.

Other Vapoursynth filters works.

Hint: When I try preview in compare mode, it produces this failure:

If I comment out loading RemoveGrainVS.dll in preview source, it works.
But I don't know how to similarly fix encode .vpy script

Thank you.
