Metahuman eyelid twitching in render

Hi guys, I’m in a bit of a pickle here.
I notice whenever I try to render a scene with my metahuman characters. Longer eyelashes from female character tend to twitch rapidly in render scene as well as the eye lid sometimes.

This only shows up occasionally during setting up so I didn’t pay to much mind about it, but now I can’t stop it from happening in both render and viewport.

I searched over the internet for weeks and no seems to have a similar proble. Note that this is not a hair flicker/disappear after some distance LOD problem this is eyelash and eyelid twiching aggressively during render.

If you have any insight I would really appreciate it.

The upload video is one of the examples. I didn’t touch any setting so all should be default.
