Resolved PhysicsBody on GameObject prefab: error when creating Entity

I have a GameObject prefab that I first convert to an Entity with

StaticClass.entityPlayer = GameObjectConversionUtility.ConvertGameObjectHierarchy(prefabPlayer, settings);

and then instantiate with

StaticClass.entityPlayer = em.Instantiate(StaticClass.entityPlayer);

. The latter causes an error:

However when I remove the PhysicsBody component from my prefab it goes away:


I've tried messing with the PhysicsBody component settings but none of them remove the error. I've also tried adding it in code (

em.AddComponent<PhysicsVelocity>(StaticClass.entityPlayer);

) and it does the same thing. I'm using 0.6.0-preview.3 for com.unity.physics and no later version is shown.

I'm using 0.15.0-preview.21 for com.unity.collections, and updating to 1.1.0 causes an error in Jobs, and updating that (from 0.8.0-preview.23 to 0.11.0-preview.6 or preview.5) causes over 100 errors in Entities (0.17.0-preview.42)...so I'm on 0.15.0-preview.21 for com.unity.collections.

Does anyone have a clue why this could be happening and/or how I fix it?

 

Try tertle's solution from this thread:
2021.2.8f1 broke AsDeferredJobArray and deferred jobs - Unity Forum

 

That worked, appreciate the link.
