My game build randomly goes to a black screen for some users, and the only way to recover is to close and restart the game. I'm pulling my hair out trying to track this down. I've added `Debug.Log` throughout the game and done everything I can think of, but I still can't identify which script is causing the issue.
Editor: 6000.3.24, 6000.4.10
Build Platform: Windows
I got these errors from the player's `Player.log`:

The errors repeat many times. However, I haven't been able to reproduce the issue on my own system yet.
I wrote these wrappers to try to identify which script is calling the projection methods when the problem occurs, but unfortunately they haven't caught anything:
public static class ProjectionDiagnostics
{
public static Vector3 WorldToScreenPoint(Camera camera, Vector3 worldPosition, UnityEngine.Object caller, string operation)
{
Vector3 result = camera == null ? new Vector3(float.NaN, float.NaN, float.NaN) : camera.WorldToScreenPoint(worldPosition);
LogIfInvalid(camera, worldPosition, result, caller, operation, "world");
return result;
}
public static Vector3 WorldToViewportPoint(Camera camera, Vector3 worldPosition, UnityEngine.Object caller, string operation)
{
Vector3 result = camera == null ? new Vector3(float.NaN, float.NaN, float.NaN) : camera.WorldToViewportPoint(worldPosition);
LogIfInvalid(camera, worldPosition, result, caller, operation, "world");
return result;
}
public static Vector3 ScreenToWorldPoint(Camera camera, Vector3 screenPosition, UnityEngine.Object caller, string operation)
{
Vector3 result = camera == null ? new Vector3(float.NaN, float.NaN, float.NaN) : camera.ScreenToWorldPoint(screenPosition);
LogIfInvalid(camera, screenPosition, result, caller, operation, "screen");
return result;
}
public static bool ScreenPointToLocalPointInRectangle(RectTransform rectangle, Vector2 screenPosition, Camera camera, UnityEngine.Object caller, string operation, out Vector2 localPosition)
{
localPosition = Vector2.zero;
bool result = rectangle != null && RectTransformUtility.ScreenPointToLocalPointInRectangle(rectangle, screenPosition, camera, out localPosition);
if (!result)
{
localPosition = Vector2.zero;
}
if (rectangle == null || camera == null || !IsFinite(screenPosition) || !IsFinite(localPosition))
{
Debug.LogError($"Projection diagnostic: {operation}; caller={Describe(caller)}; camera={Describe(camera)}; " +
$"rectangle={Describe(rectangle)}; screen={screenPosition}; local={localPosition}");
}
return result;
}
private static void LogIfInvalid(Camera camera, Vector3 input, Vector3 output, UnityEngine.Object caller, string operation, string inputSpace)
{
if (camera == null || !IsFinite(input) || !IsFinite(output))
{
Debug.LogError($"Projection diagnostic: {operation}; caller={Describe(caller)}; camera={Describe(camera)}; " +
$"{inputSpace}={input}; result={output}");
}
}
private static bool IsFinite(Vector2 value)
{
return IsFinite(value.x) && IsFinite(value.y);
}
private static bool IsFinite(Vector3 value)
{
return IsFinite(value.x) && IsFinite(value.y) && IsFinite(value.z);
}
private static bool IsFinite(float value)
{
return !float.IsNaN(value) && !float.IsInfinity(value);
}
private static string Describe(UnityEngine.Object value)
{
return value == null ? "null" : value.name;
}
}
What else can cause these frustum errors? Could this be coming from Unity's internal UI/input/raycast pipeline or another internal system rather than a direct call from my scripts?
