How to reproduce:

1. Open any (new) project
2. Import the attached script
- Observe the compilation error
- The error happens because 3 of the arguments have no default value and are therefore not optional.
- Only happens for SphereCast, other multiscene queries work as intended
- Non-multiscene/default scene queries are not affected

Code in the script:

using UnityEngine;

public class ThisShouldCompile : MonoBehaviour
{
void Start()
{
RaycastHit[] hits = new RaycastHit[1];
int number = new PhysicsScene().SphereCast(Vector3.zero, 1.0f, Vector3.forward, hits);
}
}
