I do not think it is something of drivers, but of the same configuration of the eyebrows ... In others with fibermesh, there is no problem, however, this has some bones that I do not know why the creator has put it. If I do it only with CPU, it does render. If I change it to Cinema 4d, it leaves a structure above the head and with render engines like vray, arnold, octane, I don't see anything. I will try to turn them into a normal prop, like all of them. Thank you, @sonytony
