iPad: Line Renderer causes crash on on startup

Hey guy´s

What i try to do : Have a LineRender where i can set the position of two points to be the position of two GameObjects which are animated, so the two points of the LineRenderer follow the Gameobjects.

it is all working fine for windows and Mac but on iPad it causes a crash on startup.

So i tried to display just a normal Line Renderer with the default settings but even then the app crashed on start.

Are there any restrictions on Unity iOS concerning the Line Renderer. I know that iOS does not support Dynamic Type Settings, but the default LineRenderer should work i think?

Thank´s for your help :)
