I'm having the exact same issue but only in builds uploaded to TestFlight. The steps to reproduce are:Launch the appForce-quitWait a few seconds and iOS crash alert appears.There's no crash log for this when connecting my device to Xcode. If I perform the same steps on the App Store build (which is the same one as the one in TestFlight) the alert doesn't appear, so this appears to be a problem only with builds uploaded to TestFlight.
