hairs problemes Genesis 8

Hello everyone, and Happy New Year :) A few days ago I started a scene with Underbelly (his hair and beard), everything was fine. I continued it a few days later and I have problems with his hair, his beard, his facial hair and his eyebrows! What happened? I even have this problem if I start a new scene...
I use Daz Studio 4.22.1.41, my Nvidia driver 546.33

Hi. yes, this character. I don't understand why I have problems with his eyebrows, beard, hair... but it also happens to me on others...
The same scene with Daz Studio 4.22 (non beta), will be great...!? What can I do to "reset" the beta version?
Is that image a real render or just an Iray Preview in the viewport?
It's a real render...
