Unreal Engine 5.2 Released

Hi! I have a project that work since 4.21. The materials using 16/16 texture sample. But in UE 5 . 2 this materials doesn’t work. They say [sm6] Shader using to many texture sampler 17/16. If I remove one and try to save it I get the same answer again. If I remove one again, It works. The the material graph showing the correct number only when I try to save get this message:\ Any gues what changed?
