    Hello,

    I'm seeing issues with my app since i implemented ARFoundation.
    There is a huge increase in crashes and Sentry gives this log:

    Code (CSharp):
    1. Exception Type: EXC_BREAKPOINT (SIGTRAP)

    I was hoping someone could give me any clue where to look or any insight on what UnityARKit_Camera_GetTextureReleaseCallbackHandle exactly does.

    I'm using Unity 2021.3.11f1
    ARFoundation 5.0.2
    Apple ARKit 5.0.2

    The App uses the image target technique to show AR

    Thank you in advance for any replies :)

    Hi, I've got exactly the same crash as you did. Could you share you method to solve this problem?

    @Sunday_Chou your issue is likely due to a bug in your current version of the Apple ARKit XR Plug-in. The quickest workaround is to disable multithreaded rendering in your project settings.

    We are also rolling out patches right now that should address this: 4.1.13, 4.2.7, 5.0.3, and 5.1.0-pre.2. At time of writing, 3 of these 4 patches are available now, with 5.0.3 currently in process. If you are on AR Foundation 5 and can't disable multithreaded rendering, my recommendation would be to revert to 5.0.0-pre.12 until 5.0.3 is available to avoid possible crashes.
