MetaHumans Hair renders wrong in the viewport

Hello
I am trying to create a short cinematic with metahumans
I got everything working propely except the hair…it was working when suddenly it changed to a purple/orange color…
I hapens in the viewport but in the blueprint it looks great…
I tried playing with the LOd settings and rebuilding he lighting/project and the lights ect…with no help…
I am using an Nvidia RTX 3080 and a powerful pc so i dont think its the computer…
Appreciate any help!
Thanks!
