Sun Flare Problems

All of a sudden, my light flare isn’t working. It used to work, but now it doesn’t. I’m including a screenshot of the light in inspector. As my skybox is dark, I can see what appears to be a plane on which, I imagine, the flare texture is rendered (screenie also included). From this, I can surmise that it is trying to render the flare, but can’t for some reason.

did you add any kind of collider around the camera ? the sunflare is blocked by anything that can interact with physics !
