Meta Quest Build Crash using OpenGLES3 (Unity 2022.3.8f1)

[MadisonCF]

Having a very consistent crash when running builds on the Quest Pro and Quest 2 devices using Unity 2022.3.8f1 with Oculus Integration SDK v56.

In a lot of cases the build will crash immediately on launch when loading into the scene. However I tracked down a very specific simple way to replicate it

• Make an empty scene (Other than the VR rig)
• add a 3D object into the scene behind where the player will be facing
• deploy the build
• Launch the app facing away from the object (It helps to look up with the headset)
• App should be working fine
• Turn around and look at the object
• observe crash

Following the information in this thread we were able to find a fix by changing the graphics API to Vulkan, however this is not recommended by Meta so another solution would be ideal, perhaps there is a specific setting we need to change although we are using the recommended setup from Meta

Here is the stack trace of the crash

@MadisonCF This looks like a good bug report if you wouldn’t mind filing a bug. Note that Unity does not track bugs reported in the forums :

Is a forum post the same thing as a bug report?
No. The forums can be a great way to seek advice from the development community, but Unity does not track bugs that are reported in the forums. To file a bug report for the Unity Editor or any Unity-published packages, use the in-Editor bug reporting tool: Unity QA: Building quality with passion.

Thanks I will do that

@MadisonCF Hi. Do you happen to have raised a bug report with a reproduction project for this matter?

[Hound1162]

I’ve noticed that when upgrading from 2021.3 to versions beyond 2022 in a project with OpexXR+XRI, there is an error originating from lib/arm64/libunity.so. Is this issue still under investigation? Switching to Vulkan as a workaround prevents crashes, but due to system specifications, OpenGles3 is required, so upgrading from 2021 onwards is currently not possible as long as this issue persists

[djhatvr]

Has anyone found a workaround for for making a Dev Build for Quest on 2022 yet?

[Hound1162]

This bug was caused by a bug that occurred when setting another FBX to the OpenGL or XRI controller.
If there is a reason why you cannot change to Vulkan, you need to create a minimal project and investigate what is the cause.
We also recommend using 2022.3.12 or later,
openxr recommends not using 1.9.1 and downgrading or upgrading to 2022 until bugs are fixed

[Alex_Heizenrader]

I can confirm, crashes in 2022.3 with openGL on launch but not on Vulkan, however we cannot switch due to project requirements
