Why does my character face glitch black iClone UE5 livelink motionlive

Hi why do my characters faces glitch black when using depth of field in cinematic cameras? Happens mostly around my mouth jaw and neck.

Im using UE5 with iClone livelink and using motion live to animate my face via iPhone live face app.

I found out it only happens when I have ray traced shadows on my light for my character… But I need it otherwise it doesn’t look right
