Looks like some anaglyph content. (then one would probably go from a3D naglyph to 3D sbs and drop one side to get 2D)
Assuming it's not, I did a quick test trying some ChromaShift/ChromaShiftSP (
https://imgsli.com/MzQ2NDIz/), but then maybe shifting RGB planes instead would be better.
Maybe shift is different between different fields,..
I'll have another look at it after work.
Got a sample of an unprocessed source? YUV444P12 doesn't seem like it's the native format.

I will create one with the native.
Shift+BasicVSR+++ it's very good. How do I get to that?
I tried the ChromaShiftSP though and this scene was pretty right but I suppose the result varies from scene to scene.
Thanks!
BasicVSR++ comes with the torch-addon

(I applied BasicVSR++ only on the chroma planes, not the luma plane)
Also do you have a source sample that is untouched? (not resized and whatever was done to the file or is this the only source?)

Ps.: tried shifting RGB planes => stupid idea doesn't help
