Error in animation during Eros Scene

[x92TOKYO]

Hello. Im japanese, there might be a difficulty in reading my post. Some phrases I used machine translation so I felt like an idiot. I will do my best, this is an very frustrating thing.
This isn't happen with all scenes. Only some. During certain Eros scene, there is an error in Timeline playback.
The Eros character isn't moves her upper body, only face and tail sway. Also, the hand movement was observed. It creates a broken animation. Please check out the image.

Spoiler: Image

The man and penis moves correct. It is a really strange fellatio in which a frozen girl breathes violently on the penis that acted with a life of it's own.

So I became unsure what causes the error. I have downloaded all Eros mods from the artist page. Additionally, I downloaded newer and older timeline plugin. However, none worked.
I changed her pose to T-POSE with no succeess. I changed character with no success.
It is a brand new clean Koikatsu！install with Better Repack RX22.

I ask you to help me, please, if anyone is aware of a solution to this. Thank you very much！！！

Extra note: It happen in some Jabobco scene, not all but certain movements are just missing！It's driving me crazy！！
