Spatial Anchors in Unity - DLL not found Exception on HoloLens 2

[ArDevKarl]

I installed Azure Spatial Anchors using the MRTK Feature Tool following the instructions of this page: https://learn.microsoft.com/en-us/azure/spatial-anchors/how-tos/create-locate-anchors-unity

Versions:

• Core v2.13.3
• Windows v2.13.3
• OpenXR v1.8.0 (installed but still using Windows XR)
• Unity 2020.3.42f1
• MRTK v2.8.2.0
• Device: HoloLens 2 - Windows Holographic 22H1

I'm using Windows Mixed Reality as XR-Plugin.

I'm crating a new CloudSpatialAnchorSession with my credentials (ID, Key and domain). To create a now anchor, I'm using the code provided in the docs.

Now all I get is a DllNotFoundException: "DllNotFoundException: AzureSpatialAnchors Microsoft.Azure.SpatialAnchors.CloudSpatialAnchorSession..ctor () (at Library/PackageCache/com.microsoft.azure.spatial-anchors-sdk.windows@4bce2833f5cd/Runtime/AzureSpatialAnchorsBridge_Windows.cs:2546)"

(added UnityPlayer.log for reference) UnityPlayer(3).log

Is it possible this Unity Version (2020.3.42f1) is not supported, or Windows XR support does not work with Spatial Anchors?

@ArDevKarl Thanks for bringing this to our attention. I'm going to assign this to the document author so they can take a look at it accordingly.

Updated to v2.14.1 still DllNotFoundException. Can I expect any answers here?
