To query managed components in Unity ECS without Burst compile errors, use SystemAPI.ManagedAPI.Query inside a SystemBase and ensure the system is not marked with [BurstCompile]. This keeps managed access on the main thread.

The correct way to access a managed singleton configuration in Unity DOTS is using SystemAPI.ManagedAPI.GetSingleton. This retrieves managed IComponentData safely per frame without violating Burst safety restrictions.

Yes, you can use SystemAPI.Query for mixed managed and blittable ECS components within a SystemBase. This allows reading and writing hybrid per-entity state while maintaining correct non-Burst execution paths.

You should place a hybrid sync system for GameObject-related behavior in ECS within the PresentationSystemGroup or a dedicated HybridSyncGroup. This ensures managed UnityEngine components sync correctly on the main thread.

Your Unity DOTS system crashes when accessing UnityEngine components because managed types cannot be used in Burst-compiled systems. You must use SystemAPI.ManagedAPI and disable Burst compilation for that specific system.
