Reflections Error please help!!!

Hi I need help with a problem with Reflections that i've come through and I cant solve it.

As seen in the photo the material is "damaged" and on any object that I apply it(The cube). I checked everything and what I found is, if I turn off reflections(In the inspector) the rare color disapears.If I increase the metallic or smoothness bar it increases and vice versa

Please Im working on a game and this came through and now I cant fix it.

if any info is needed to solve the problem let me know.

(the only thing I know is that, going in the graphics menu if I toggle some of the stuff the problems gets solved temporaly.)
