Initial Project load causes Gizmo.Draw.WorldText to sometimes fail and spam exceptions

Describe the bug

Alright.. this is a weird and random one. I Have a DebugComponent i create in a Custom MapInstance that puts it onto objects that i haven't implemented yet The map was made a year ago and has Entities that don't exist anymore.

I put the Component onto it during the OnCreateObject Method and it consists of a single DrawGizmos() override Sometimes when i open the project up it just causes an exception and spams the console full of errors until i restart.

Log and Stacktrace is in Media/Files

here is how i do it

----inside of the OnCreateObject function------------------------
if ( kv.TypeName.StartsWith( "wg_" ) && !handledTypes.Contains( kv.TypeName ) )
{
    Log.Info( $"Object type not found for {kv.TypeName}" );
    var obj = go.Components.Create<MapLoaderDebugShow>();
    obj.object_type = kv.TypeName;
    return;
}
---------------------------------------------------------------------

public class MapLoaderDebugShow : Component
{
    float rot;
    public string object_type { get; set; }
    protected override void DrawGizmos()
    {
        base.DrawGizmos();
        rot += Time.Delta * 20;
        if ( rot > 360 )
            rot = 0;
        using ( Gizmo.Scope( "debugText" ) )
        {
            Gizmo.Draw.WorldText( $"{object_type} ISN'T IMPLEMENTED", new( Vector3.Up * 32, Rotation.From( 0, rot, 90 ), 0.05f ), size: 64 );
            Gizmo.Draw.Color = Color.Red;
            Gizmo.Draw.LineBBox( BBox.FromHeightAndRadius( 32, 16 ) );
        }
    }
}

To Reproduce

make a custom MapInstance
Add the component to any object (i'd assume it works on any object)
restart the game until it errors / reload the project using the launcher

Expected behavior

It should just render the WorldText and not cause an exception on project startup

here is the Log from one of the times it happend: Log.log

it just prints this over and over again
