FUZZY JITTERING IN SHADOW WITH METAHUMAN?!

I’m experiencing this issue in Unreal Engine, and it happens sometimes when my Metahuman is in the shadows. The character gets this strange jitter, both on the head and the face. I’m still fairly new to Unreal, so it would be a huge help if someone out there could assist me with this problem. I’ve tried searching on YouTube, but it seems like there aren’t really any relevant results. I’ve attached images below.
