[HELP] Can't run Cnr2 noise reduction

[Selur]

Vapoursynth script:

# Imports
import vapoursynth as vs
# getting Vapoursynth core
core = vs.core
# Loading Plugins
core.std.LoadPlugin(path="C:/Program Files/Hybrid/64bit/vsfilters/DenoiseFilter/Cnr2/libcnr2.dll")
core.std.LoadPlugin(path="C:/Program Files/Hybrid/64bit/vsfilters/SourceFilter/LSmashSource/vslsmashsource.dll")
# source: 'S:\HybridOUT\GBH-Liv-SVHS-DMR_SD-qtgmc_new.mov'
# current color space: YUV422P10, bit depth: 10, resolution: 732x564, fps: 25, color matrix: 709, yuv luminance scale: limited, scanorder: progressive
# Loading S:\HybridOUT\GBH-Liv-SVHS-DMR_SD-qtgmc_new.mov using LWLibavSource
clip = core.lsmas.LWLibavSource(source="S:/HybridOUT/GBH-Liv-SVHS-DMR_SD-qtgmc_new.mov", format="YUV422P10", cache=0, fpsnum=25, prefer_hw=0)
# making sure input color matrix is set as 709
clip = core.resize.Bicubic(clip, matrix_in_s="709",range_s="limited")
# making sure frame rate is set to 25
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# Setting color range to TV (limited) range.
clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)
# adjusting color space from YUV422P10 to YUV444P8 for vsCnr2
clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P8, range_s="limited")
# chroma denoising using VsCnr2
clip = core.cnr2.Cnr2(clip=clip, mode="oxx")
# adjusting output color from: YUV444P8 to YUV422P10 for ProResModel
clip = core.resize.Bicubic(clip=clip, format=vs.YUV422P10, range_s="limited")
# set output frame rate to 25.000fps
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# Output
clip.set_output()

looks correct.

Encoding call:

also seems correct.

Don't really see the problem from the script and calls.
Do the colors in the Vapoursynth Preview look correct and are only wrong in the output or are the colors in the Vapoursynth Preview already wrong?
