Object reference not set to an instance of an object in the editors NavMeshToolbarWidget.cs line 14

Describe the bug

I've created 3 fresh projects and after transferring all of my assets over, if I close the project and reopen it, I get hit with this error which prevents further development, Scene view is white, no scene is autoloaded anymore and once I successfully open and run a scene the game view doesnt run the game just the default catalog (most likely because the game cannot run)

To Reproduce

Create a project I assume create a scene asset with a missing script (which is in the project? just isn't found?) Save/Close the project Open it again and see a white scene view

Expected behavior

The project should load the scene and since the components are inside of the /code file path (in a subfolder) they should be loaded and the game should run or atleast run the scene view without 'Interop' spamming Object refere4nce not set to an instance of an object

Media/Files

Example rudimentary script which does not load to help with reproducing the issue

`using Sandbox; using System; using System.Collections.Generic;

public class NpcGereric : Component { [Property] public Vector2 velocity = new Vector2 (0, 0); [Property] public CharacterController controller; List eyes = new List(); protected override void OnUpdate() { if ( controller.IsValid() ) { Vector3 additionalForce = Vector3.Zero; if ( !controller.IsOnGround ) { additionalForce += new Vector3( 0, 0, controller.Velocity.z - 600 Time.Delta ); } //controller.Velocity = GameObject.Transform.Rotation.Forward velocity.x + GameObject.Transform.Rotation.Right velocity.y + additionalForce; controller.Velocity = new Vector3(velocity.x ,velocity.y ,0) + additionalForce; controller.Move(); } //controller.MoveTo(GameObject.Transform.Position + GameObject.Transform.Rotation.Forward 64 * Time.Delta, true ); }

public void RegisterEye( Eye eye )
{
    eyes.Add( eye );
}

public void UnregisterEye( Eye eye )
{
    eyes.Remove( eye );
}

} `

Additional context

Fairly standard project which uses a file structure similar to source1 and HL:A files (IE: models, animgraph, material folder paths)

I wish I thought to add this earlier and this is not the bump the post as it hasn't even been categorized yet:

The projects do not load, and to open to show said issues has to be forcibly opened by opening the .sbproj file in the projects root directory, otherwise in the s&box project launcher the project will load until 10% and then cancel with no further information.

This should no longer be a problem for you
