URGENT - weird textures and black banding only on build

I have this problem when building my game, the screen goes like this everytime. I’ve tried multiple builds changing settings, disabling objects, lowering texture qualities etc etc. but can’t seem to fix it. If somebody knows what the problem is it would be greatly appriciated

Have you tried adding a light to your project, and if you have, have you tried turning up the intensity of the light?

Did you tried changing the game resolution ?
