It’s happening whenever the app goes in background or minimized. Reopening from menu or unlocking, exactly this error is coming up. Any update on this issue?

It seems there is some bug at ExpoCameraView.kt:

       val faceDetectorProvider: FaceDetectorProviderInterface by moduleRegistry()
          faceDetector = faceDetectorProvider.createFaceDetectorWithContext(context)
          pendingFaceDetectorSettings.let {
           faceDetector?.setSettings(it)
           pendingFaceDetectorSettings = null
          }

I delete lines of code above, my app works well and never crash, I guess there is some bug about face detection, but I never use face detection in my app.

Any help is appreciate
