I made a script to switch through two different camera’s for locking onto an enemy (My logic isn’t finished yet but not the point).
I first had a public variable called CinemachineVirtualCamera and referenced my gameobject with the CineMachine virtualCamera to that variable.
But it gives me this error:

Severity Code Description Project File Line Suppression State Warning CS8032 An instance of analyzer Unity.Properties.SourceGenerator.PropertyBagGenerator cannot be created from C:Program FilesUnityHubEditor2022.3.25f1EditorDataToolsUnity.SourceGeneratorsUnity.Properties.SourceGenerator.dll: Could not load file or assembly 'System.Runtime, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. Het systeem kan het opgegeven bestand niet vinden.. Assembly-CSharp C:Program FilesUnityHubEditor2022.3.25f1EditorDataToolsUnity.SourceGeneratorsUnity.Properties.SourceGenerator.dll 1 Active

but the script does exactly what I tell it to do.

But when I referenced the variable through the start method with getcomponentinchildren<CinemachinVirtualCamera>() I didnt get the error but the script didnt do what I wanted it to do

should I just ignore the warning or am I doing something wrong?

This is my whole script:

[Header("Bools")]
public bool locked;

[Header("Lock on settings")]
public LayerMask enemyLayer;
public float radius;
public float maxAngle;

//private void Start()
//{
//    enemyCamera = GetComponentInChildren<CinemachineVirtualCamera>();
//}
public void Update()
{
    Inputs();
    PlayerLookAt();
}

void Inputs()
{
    if (Input.GetKeyDown(KeyCode.Mouse1) && !locked)
    {
        if (enemyCamera == null)
        {
            print("Waarom werk jij niet");
        }
        enemy = CalcEnemyLock();
        enemyCamera.LookAt = enemy;
        SetCamera();
    }
    else if (Input.GetKeyDown(KeyCode.Mouse1)  && locked) 
    {
        locked = false;
        SetCamera();
    }
}
Transform CalcEnemyLock()
{
    Collider[] nearbyEnemy = Physics.OverlapSphere(transform.position, radius, enemyLayer);
    float closestAngle = maxAngle;
    Transform closestTarget = null;

    if(nearbyEnemy.Length <= 0)
    {
        return null;
    }

    for(int i = 0; i < nearbyEnemy.Length; i++)
    {
        Vector3 dir = nearbyEnemy[i].transform.position - mainCamera.transform.position;
        dir.y = 0;

        float angle = Vector3.Angle(mainCamera.transform.forward, dir);
        if (angle < maxAngle)
        {
            closestTarget = nearbyEnemy[i].transform;
            closestAngle = angle;
        }
    }
    locked = true;
    return closestTarget;
}
void SetCamera()
{
    if (locked)
    {
        freeLook.Priority = 10;
        enemyCamera.Priority = 20;
    }
    else
    {
        freeLook.Priority = 20;
        enemyCamera.Priority = 10;
    }
}
void PlayerLookAt()
{
    if (locked)
    {
        player.LookAt(enemy);
    }
    else
    {
        player.LookAt(null);
    }
    
}

I tried referencing it in different ways so the cinemachinevirtual camera variable wouldnt be null but the script only worked when it was null
