Unable to read iOS Crash Log - is it symbolicated?

Question

Is this iOS crash log symbolicated? It came from beta app review, so didn't auto symbolicate, but I imported it into the device crash logs, which apple said would use the dsym file to symbolicate.

If it is, then how do I interpret this and where the problem is? It doesn't crash on any of my devices or simulators, or our internal testers...

Apple said it crashes on launch and when clicking the button on the home screen to start.
