The error happens when trying to read value of type GameObject

Hi @elliotc-unity . Did any dots developer aware of this issue? I need unofficial hotfix for me to fix it locally. I need to get 0.50 up and running asap.

I don’t know what’s causing it, but an internal slack search suggests that clearing the entity dependency cache has sometimes fixed it in the past. Can you try that and let us know if it fixes it?

@elliotc-unity

This error caused by the following piece of code:

[System.Serializable]
    public sealed class Projectile : IComponentData
    {
        [System.NonSerialized] public GameObject AppearanceInstance;
        [System.NonSerialized] public GameObject ExplosionPrefab;
    }

the error is gone when I removed the [NonSerialized] part

I had some TextMeshPro assets in my subscene which I deleted and it fixed the issue for me.
