使用URP之后，Unity报错：显示不正常
NullReferenceException: Object reference not set to an instance of an object
UnityEngine.Rendering.Universal.UniversalAdditionalCameraData.get_cameraStack () (at Library/PackageCache/com.unity.render-pipelines.universal@10.6.0/Runtime/UniversalAdditionalCameraData.cs:236)
URPCameraSetter.Start () (at Assets/Scripts/Eyeah/GameSystem/URPCameraSetter.cs:16)
解决：
设置这个URP的Asset丢了
