How to fix broken mesh in LineRenderer?

Question

Unity

I make predictions about the direction of the ball. The direction is rendered using LineRendera. When an angle is too sharp, the render mesh will warp (as if twisted around an axis) as you can see in the screenshots below. Because of this, the material looks incorrect. Is it possible to fix this?

PS I've searched quite a lot of Russian-speaking and English-speaking forums, but I haven't found an answer yet.
PSS If the complexity of the question was reduced to "simple", then why does no one know the answer?
