Possible Burst bug

I got a function that is correctly compiled by burst, but then when it runs, it says:

E:\RobocraftX\Assets\Code\RobocraftECS\Contexts\Scenes\Character\Camera\Engines\LocalCameraSphereCastEngine.cs(136,25): Burst error BC0102: Unexpected internal compiler error while processing function `IL_009f: ldfld System.UInt32 Svelto.ECS.EGID::entityID args(IL_009a)`: System.InvalidOperationException: The struct field Svelto.ECS.EGID Svelto.ECS.Extensions.Unity.UECSSveltoEGID::egid's struct comes from an unaddressable source: IL_0095: call !0 Unity.Entities.ComponentDataFromEntity`1<Svelto.ECS.Extensions.Unity.UECSSveltoEGID>::get_Item(Unity.Entities.Entity) args(IL_008e, IL_0093)

@xoofx shall I open a bug report for this or it means something that I didn't get it yet?

The code that breaks is this:

sphereCastEntityStruct.entityID[index++] = SveltoEgidGroup[e].egid.entityID;

where

[ReadOnly] public ComponentDataFromEntity<UECSSveltoEGID> SveltoEgidGroup;

the EGID struct is this:

[Serialization.DoNotSerialize]
[Serializable]
[StructLayout(LayoutKind.Explicit)]
public struct EGID:IEquatable<EGID>,IEqualityComparer<EGID>,IComparable<EGID>
{
[FieldOffset(0)] public readonly uint entityID;
[FieldOffset(4)] public readonly ExclusiveGroupStruct groupID;
[FieldOffset(0)] ulong _GID;
