Integration SDK 54.1 not working in Unity

I can't get SDK 54.1 to work with Unity at all. Here are my steps:

1) Create new core graphics project

2) swap to Android

3) Install XR integration, set to "Oculus"

3) import Oculus Integration SDK 54.1

After the lengthy install, Unity re-boots (as usual). When it re-loads, even before entering run  mode, about every 15 seconds part of the OVRPlugin script runs a function named "ovrp_QplTrackBegin" (or something similar) and a EntryPointNotFoundException is thrown, like it cant find a function in the OVRPlugin.dll. Nothing VR works from that point forward - even panels with VR settings are blank. I've tried older versions of Unity - going back as far as the last 2022 LTS version and a whole slew of other things - I cant get it to work at all. I've even refreshed my Windows 11 pc and started from scratch. From my point of view - v54.1 SDK doesn't work at all. Is anyone actually using it? I find it hard to believe that would be true. Has anyone encountered this and found a fix/work-around?

      Hey I have the same problem, Ive tried everything to fix.  I lost my whole setup.  Did you figure out a work around?

      Well... I have it working now, but I tried many things, and I'm not sure which one actually made a difference. My two most probable "fixes" are...

      1) I usually change over to Android before adding the XR Integration plugin and the Oculus Integration SDK, to minimize the assets that need to be converted. In the project where it finally worked, I left it as a Windows project, installed all the VR stuff, and only THEN switched over to the Android build. (took a long time to convert everything).

      2) Before I imported the Oculus Integation SDK, I used the "re-download" button before the import button to make sure I had a good copy. I hadn't tried that before.

      Hopefully one of these two tips will work for you - I'm not sure why it's working today and wasn't yesterday. Let me know if one of those works for you. If not, I'll put more effort into trying to remember the other things I tried.

      Hi Thanks for the tips. Is that still working for you? I've tried your way, it only worked once. If restart the unity editor, the DLL issue is back again.

      Alright... new info. Try this work-around:

       

      1) Without uninstalling the recent editor version (I'm using the new one release today 2023.1.5f1), install the most recent LTS version editor: 2022.3.5f1 (LTS)

      2) Create your project in 2022.3.5f1 (LTS)

      3) I left my project on Windows - you may be able to switch it to Android at this point.

      4) Install XR-Plugin management, and set to Oculus

      4) Install Oculus 54.1 Integration SDK and apply settings / fixes per its wizard.

      5) Close project and re-open it with the new editor, and switch to Android.

      Let me know if it works for you, too.

      Yeah - the difference this time is that I used the older editor to create the project, and then upgraded it to the new version.

      v55.0 just dropped, and my very first project worked as it should! Testing it more thoroughly now,

      Hi Jeff, I've started a new project and tested V55, it like before only works when I started a new project, once the project is saved and Unity editor closed, and opened it again, the same issue comes back again.  (This is just looking at the 'HandGrabExamples' template scene in the package Interaction folder) How's yours?

      I programmed all night last night with a brand new V55 QuestPro project, testing shared anchors, spatialized audio. I had zero problems. Judging by the time you are posting your replies, getting together to try a project together may prove challenging - I'm in the U.S. near Seattle, Washington. You've just headed to sleep for the night when I get off work in the afternoon (my 3pm, your 11pm).

      Maybe send me a screen-capture video of you creating your project and then getting the errors?
