Bug Crash when using ARFoundation (android) StartedCameraController(0) Saw capture failed event, failure

We are working on an AR application with ARFoundation, but we have had random crashes, where the app just closes. These always seem to happen at random moments, and we haven't found a way to reproduce it consistently.

The error we get is:

2023/02/27 16:02:34.912 23932 23947 Error BufferQueueProducer [ImageReader-1920x1080f22u256m16-23932-0](id:5d7c00000004,api:4,p:1581,c:23932) dequeueBuffer: attempting to exceed the max dequeued buffer count (9)

2023/02/27 16:02:34.913 23932 24891 Error RepeatCaptureReq(0) Capture failed.

2023/02/27 16:02:34.914 23932 25018 Error StartedCameraController(0) Saw capture failed event, failure: android.hardware.camera2.CaptureFailure@74c66a1.

Unity version: Unity 2023.1.0a20
ARFoundation: 5.0.3
Google ARCore XR Plugin: 5.0.2

Anyone an idea what could cause and hopefully solve the crash? I know the alpha version of Unity is not ideal, but sadly I was placed on this project after the decision to use this version of Unity was taken.

 

I was able to catch a crash on a development build any this was the log:

 

We're on 5.0.3 for both and same error is happening multiple times per run.
