Question Oculus Quest - Failed to load openxr runtime loader

I'm not sure what's changed, but OpenXR is no longer working for me on Oculus Quest builds. I get this log message. Anyone have any ideas? I double checked the OpenXR settings and I do still have Oculus Quest support checked.

I recently updated to OpenXR 1.2.3, so I downgraded back to 1.2.2 to see if it would fix it. Now it just completely crashes during startup, and this is the log for the crash.

@the_real_apoxol Any ideas on this? It's preventing me from being able to release an update to my game

 

I just created a new project with OpenXR 1.2.3, and it started up just fine. Any ideas what could be wrong with my project? I tried reinstalling OpenXR and deleting the XR folder to set it all up again, but that didn't fix anything

 

Yes, I do manually restart XR after returning to the app from requesting microphone permissions. It was necessary from a previous conversation we had over XR not working after returning to the app from that.

However, XR is not starting before from the automated startup, nor after from this manual restart currently

 

The issue is I can't reproduce it in a new project, not sure what's causing it in mine. I did try building it locally though and it actually seemed to work, so it might be an issue with my automated build platform. I deleted the Library/etc folders there and rebuilding to see if it makes a difference. It takes a couple hours to do the build without the cache though, so waiting for it to finish. If that doesn't work then I have no idea what else to try

 

In my project, its currently set to initialize on startup automatically (I have issues with the manual startup that I posted about in another thread), so that's not the source of the issue. The manual restart is only on first launch after requesting the microphone permission, so it's not the source of my issue with OpenXR not working at all

 

Unfortunately, deleting the Library folder did not fix the issue. Here's the log entries from the automatic startup, rather than the manual restart from first launch

EDIT:
I tried digging through the source code of how OpenXR is initialized to see if I could track down any potential culprits to look into, but it seems that the code that triggers that error message is inside of a C++ DLL, so I couldn't go any further in debugging it

 

No I don't, just the minimum for Quest support. Not sure what else to check there

 

No, this is only affecting Oculus Quest builds. And if I build the Android version on my local copy it seems to work fine, but when built through my automated build pipeline it does not and has the OpenXR failure. It's quite strange and I have no idea what could be causing it since deleting the Library didn't resolve it

 

I just messaged you a link to it

 

Hate to necro an old topic, but I too am having this issue. My OpenXR Oculus Quest 2 build won't start. Won't even show the splash screen, and it locks me in the game infinitely loading with the animated ellipsis. This only happens in OpenXR as my title runs fine with the Oculus setting enabled instead in the XR Plug-In Management section. Either that, or it's the switch to Arm64 that's preventing my game from loading.

Can't test either exclusively since Arm64 is required for OpenXR to run. But I can say that even switching to the Oculus runtime with Arm64, my project wouldn't start. Upon switching back to Armv7, project runs again.

I'm using Unity 2020.3.21
Oculus XR Plugin 1.10.0
OpenXR Plugin 1.2.8
XR Plugin Management 4.0.7

 

Are you using Vulkan? There's a crash on startup for OpenXR right now now on Vulkan that is supposed to be getting fixed in 1.3.

 

I am using Vulkan. That's great to hear! Now I'm getting another issue when switching to OpenGLES3. Unity logo flickering endlessly on the quest build... Been spending so much more time dealing with getting the build to run okay than on actually developing my game...

 

Wonderful, thank you!
