We've found the culprit, it was a 3d-party SDK we use to record screen sessions. After downgrading to the previous SDK version the crash is gone. That SDK does a lot of method swizzling using Obj-C runtime and tracks all UI interactions, at the same time it's not open-source, so it's hard to say what was the reason.

I made a mistake in my text above saying it's an invalid instruction fetch, documentation clearly says it's an invalid memory fetch because pc counter's value is different from the exception address.

We also need this kind of feature on our project, any kind of integration with either Jira or Slack. Apple folks, is there a way to achieve that?
