Hi @KilliKrate. Thanks for the detailed report, we're seeing the same. It seems like the issue arises from one of our dependencies, Unity's WebRTC implementation (https://github.com/Unity-Technologies/com.unity.webrtc/issues/437). Unfortunately it does not seem to be high priority for them and has been around a few years.
Falling back to our old dotnet WebRTC implementation would solve the issue. But it's a bit limited by comparison, and a lot slower.
A few users in that thread seem to have had some luck messing with the Minify options in Project Settings > Player > Publishing Settings. I'll give it a go when I have some time to see if it makes any difference.
Addressed in 2ca2da67089d005b78feb6492040a3628ef09317. Workaround in v1.0.0-pre.3.
After a lot of digging, it seems like the crash arises from the Vulkan init hooks added to com.unity.webrtc in version v2.4.0-exp.7. Perhaps Oculus' OpenXR compatibility package also hooks into the same event. In the end I've rebuilt the android native plugin in com.unity.webrtc with these hooks stripped out. I've set it up as a new UPM package for Ubiq to pull in here.
This now works okay, but video streaming will probably no longer work. I also ran into another issue while working on this (#49), so we're currently falling back to the old dotnet WebRTC implementation on Android. Hopefully this works for now (we can build and get VOIP), but this will need some more attention over the next few months.
I've recently had problems building my Ubiq project for standalone VR use using ARM64. I've built the project before using ARMv7 with no issues, but with ARM64 the project seems to crash as soon as you enter the game, right after the "made with Unity" splash-screen.
After plenty of debugging I've seem to hit a dead end, so I tried building the Start Here sample with ARM64 to see if even the original sample has this problem, and in my case it has. Here's the steps to reproduce my scenario:
If you try and keep Vulkan as your preferred Graphics API you just get an infinite black loading screen. The build seems to crash most of the time (sometimes it loads unexplainably with no issues) and adb logcat reports a Vulkan-related problem if you use that, but if you switch to OpenGLES3 you just get a crash due to a null-pointer dereference (which I have no idea how to debug).
My biggest concern is that Meta only supports ARM64 applications on the store, but more importantly this issue prevents me from building with OpenXR, which is needed to create a build that supports the first Quest headset. I'd be very glad if you tried to reproduce this and tell me your results (even with a different Unity version, since it shouldn't make a difference?)
