Hi Microsoft support,

I'm having some trouble using the OpenXR branch of the MixedReality-QRCode-Sample: https://github.com/microsoft/MixedReality-QRCode-Sample with holographic remoting in both Unity Editor Play Mode and standalone. The QR code tracking function works well when deployed on the Hololens device.
I use Unity 2020.3.33f1, both MRTK 2.8.2 with MR.OpenXR 1.5 and MRTK 2.8.3 with MR.OpenXR 1.8 not work.

The QRCodeWatcher.IsSupported() function returns false and no QRCodes are added during testing. Is there any update on the sample repo? Or how can I diagnose the problem, as there are no error messages?

    Hi,

    I tried using Unity Editor 2021.3.26f1 and it worked. However, the editor crashed every time I exited Play mode. I will upgrade my Unity version and try again.

    My Hololens OS is Windows version 22621.1125.arm64fre.ni_release_svc_sydney_rel_prod.230802-0616. I'm not sure what the version of Holographic Remoting means, but I used it in the editor. I used Holographic Remoting Player 2.9.2.0 in the Hololens.

    I upgrade the MRTK OpenXR to 1.8.1 and the project did not crash after exit Play mode.
