DeGrain is the wrong filter for this, that is no grain or noise.
Looks more like a job for Avisynths DeFreq (https://avisynth.org.ru/defreq/defreq.html), Vapoursynths vcFreq (http://www.avisynth.nl/users/vcmohan/vcfreq/vcfreq.html) or Avisynths DeStripe (http://avisynth.nl/index.php/DeStripe) which are all not supported in Hybrid.
Also just saw something through my online search which looks like your problem: https://forum.doom9.org/showthread.php?t=163574
-> if you can share a few second long sample I can try looking into it some more.
