OVRAnchor.SaveResult Unknown Error -1006

Hello,
I am trying to work with OVRSpatialAnchor of the Meta Core SDK v74 in Unity 2022.3.53f1 and experience some issue on saving my successfully created, bounded and localized OVRSpatialAnchor.

Therefore I checked all OVRAnchor.SaveResult Enumerations but it turns out that the error -1006 on my result is an so far unknown error code. 

Compared with: https://developers.meta.com/horizon/reference/unity/v74/struct_o_v_r_anchor#public-type).

OVRAnchor.SaveResult.Failure: -1000 
OVRAnchor.SaveResult.FailureInvalidAnchor: -1013
OVRAnchor.SaveResult.FailureDataIsInvalid: -1008
OVRAnchor.SaveResult.FailureInsufficientResources: -9000
OVRAnchor.SaveResult.FailureStorageAtCapacity: -9001
OVRAnchor.SaveResult.FailureInsufficientView: -9002
OVRAnchor.SaveResult.FailurePermissionInsufficient: -9003
OVRAnchor.SaveResult.FailureRateLimited: -9004
OVRAnchor.SaveResult.FailureTooDark: -9005
OVRAnchor.SaveResult.FailureTooBright: -9006
OVRAnchor.SaveResult.FailureUnsupported: -1004
OVRAnchor.SaveResult.FailurePersistenceNotEnabled: -2006

Did anyone here experienced the same error code and found a solution for this issue?
