Any way to IVTC or restore this (animation)?

Here's a sample: https://gofile.io/d/jPpcsd

I've tried field matching with TFM(), but there are some combing artifacts (or blending artifacts, I'm not sure of the difference). Is there any way to get a clean IVTC out of this material or some sort of restoration?

TFM is about all you can do. Or all that I can do. It's phase-shifted, but there's a whole lot of chroma out of place. Maybe someone else has dealt with this sort of thing before.

There's a parameter in TFM called slow. Default is 1, but 2 is slower and more effective.

No great luck playing around with TFM, chroma issues still persist. Maybe AnimeIVTC could be of help...?

I actually have the material also in NTSC, which does not have these issues, but unfortunately the transfer is otherwise of lesser quality, as seen here:

you can take Luma from PAL after go to 24 and chroma from NTSC after go to 24 (not 23.976)
