OpenXR Hanging after v62 update

After the v62 update, my play in editor times had jumped to 20-60 seconds. I managed to profile and found the culprit as seen in the photo: 
While I narrowed down the issue in Unity, this happens with my packaged application, and other unity applications. I believe anything using the openXR runtime.

Things I've tried
- Uninstall Meta Quest Software and clearing all app data folders. Then re-install.
- Upgraded Graphics Drivers (I have a GTX 1080).
- Computer Restart
- Oculus Quest 2 Factory Reset

      Same issue here. I wonder if it is possible to revert to an earlier version of the Meta Link App?

      It seems like doing as much as runing the "hello_xr" example from the OpenXR Sdk can reproduce the same behavior:

      I tried replying but it seemed to make a post to this thread; my mistake.

        Interesting. I notice you have a newer card. I thought maybe having an older 1080 might have been the culprit. Thanks for sharing.

        How consistent is this for you? I'm stuck with 20 second load times minimum and sometimes 3 minutes without fail.

          For me it's been consistently around 20 seconds, I cannot recall a much longer delay. Though I have not been trying too much. 

           

          I experienced the same with Unity, Godot and StereoKit, even Unreal has the 20 second delay at first. However in the case of Unreal Engine it only seems to be stuck the first time that I run the VR Preview, after that it launches quickly as it should.

          I'm also experiencing a long delay (> 30 seconds) in my non-Unity app when attempting to create an OpenXR session with v62. I posted about this issue in the Khronos OpenXR forum:

          https://community.khronos.org/t/xrcreatesession-slow-to-return-with-meta-quest-link-runtime/110525

          Any word on when this issue will be fixed?

          tldr; You see this issue when your PC Oculus Software and Quest software are out-of-sync. Most people having issues had it when their PC software went to v62, but Quest was stuck on v60. Most don't have access to the Public Testing Channel so you'll need to install an archive for the update manually.
