AR camera freezes on application launch: StartedCameraController(0) Saw capture failed event, failure: android.hardware.camera2.CaptureFailure@d2addf1

[3ternal]

When I launch any AR app, my camera freezes and the application stops executing. This is occuring both in my personal project and in an official Unity sample: https://github.com/Unity-Technologies/arfoundation-samples/issues/1136

Furthermore, I think the crash started occuring after a recent Android security update, so it might be related to Android rather than Unity.

I think it's the same problem as described in this thread: https://forum.unity.com/threads/ar-foundation-stopped-working-all-of-a-sudden-on-android.1529341/

Note: I confirmed that execution stops by printing a message on every frame. The application gets stuck on frame 15 or so. In other words, I can confirm that the application launches correctly, but it's running into some problem with the camera and it ends up crashing.

Uninstall and reinstall google play for ar services App

Solved!

[NunoCardosoYD]

Thank you very much for the tip, I confirm this, it does solve the problem, but only temporarily, and it does not even take a new build to break it again, just a reinstall of the affected app.

In my case reinstalling Google Play Services for AR makes my app work again (both new builds or the app submitted to the store 3 months ago), but if I uninstall my app and reinstall it again (same version, a new one, an old one, doesn't matter) then it breaks again.

Fortunately, until a final fix from Google, doing the reinstall of the "Google Play Services for AR" trick at least allows development to progress, but in no way is it a fix for production, and since many Play Store apps may be affected retroactively without even noticing, I guess this will become a priority very fast, at least it should.

This is related to https://github.com/google-ar/arcore-android-sdk/issues/1634 -- a server push was sent out to everybody to fix this problem; let me know if you're still seeing this.
