[BUG] Hybrid 2022.11.28.1, y4m bad sequence header issue

[Selur]

Will look at it after work and report back.

y4m [error]: bad sequence header magic

usually indicates an issue with the Vapoursynth script
-> does the Vapoursynth preview work properly ?

At a first glance, the used script:

# Imports
import vapoursynth as vs
import os
import ctypes
# Loading Support Files
Dllref = ctypes.windll.LoadLibrary("C:/Program Files (x86)/Hybrid/64bit/vsfilters/Support/libfftw3f-3.dll")
import sys
# getting Vapoursynth core
core = vs.core
# Import scripts folder
scriptPath = 'C:/Program Files (x86)/Hybrid/64bit/vsscripts'
sys.path.insert(0, os.path.abspath(scriptPath))

# Setting color matrix to 470bg.
clip = core.std.SetFrameProps(clip, _Matrix=5)
clip = clip if not core.text.FrameProps(clip,'_Transfer') else core.std.SetFrameProps(clip, _Transfer=5)
clip = clip if not core.text.FrameProps(clip,'_Primaries') else core.std.SetFrameProps(clip, _Primaries=5)
# Setting color range to TV (limited) range.
clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)
# making sure frame rate is set to 25
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
clip = core.std.SetFrameProp(clip=clip, prop="_FieldBased", intval=1)
# setting field order to what QTGMC should assume (bottom field first)
clip = core.std.SetFrameProp(clip=clip, prop="_FieldBased", intval=1)
# Deinterlacing using QTGMC
clip = havsfunc.QTGMC(Input=clip, Preset="Fast", TFF=False) # new fps: 25
# make sure content is preceived as frame based
clip = core.std.SetFieldBased(clip, 0)
clip = clip[::2]
# set output frame rate to 25fps
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# Output
clip.set_output()

looks fine, and so does the encoding call:

Ps.: One only thing that seems strange is that Hybrid is installed under 'C:/Program Files (x86)' as a 64bit application it normally should be installed under 'C:/Program Files'. (Reencoding the file, works fine here)
