My project uses the URP lights that were well configured, but a while ago they stopped working, they even disappeared in the menu, the lights that are in the scene do not work and there is the following error: "error 2d renderer data must be assigned to your urp asset or camera". I am not able to fix this error.

Have you set it to Quality setting?

Did you set it to Graphics setting?

Is the Camera's Renderer specified as Default Renderer or 2d's Renderer Pipeline?
