Animation artifacts on metahuman

Hello everybody!

During testing 5.2 pipeline of animating Metahumans a problem appeared.
Metahuman that I updated from 5.0 to 5.2 seems to have artifacts on its chin. But artifacts only appear when the chin is moving down. During any other movement it seems ok although even the slightest chin movements down seem to create glitches. All of my other MetaHumans look fine with this animation

I tried to work around materirals but im fairly new to the programm and it didnt help with the problem. Seems like only “World Normal” is broken though, but i have no idea how to solve it
