'Sequence contains no elements' ERROR for Entity debugger window

Hi all,

I am running 2019.2.0f1 unity and have recently experienced huge issues with the Entity debugger window. Whenever I open or focus on the Entity debugger window I get a huge number of assertions. I have tried with just the simplets ECS script (see below), but have repeated errors (see below). Again this only ever happens when I focus the Entity debugger window. Thanks for any feedback.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Unity.Entities;
5.  
6. public class Testing : MonoBehaviour
7. {
8.     // Start is called before the first frame update
9.     void Start()
10.     {
11.         EntityManager entityManager = World.Active.EntityManager;
12.  
13.         entityManager.CreateEntity();
14.  
15.     }
16.  
17. }

Try adding components to the entity. It could be due to 0 components attached debugger is getting confused.

 

I could create an empty entity before

Moving mouse between any GUI element, generate these errors. But only when Entities are displayed in debugger.
