Apps crashing when distributed via TestFlight

I have strange problem: app runs well when starting from Xcode, but it`s instantly crashes when distributed via TestFlight.

I have tried:
  • different configurations. All configurations runs ok from desktop

  • Archiving and then manually (via devices in xcode) install .app from archive - also runs ok.

All the crashlogs in TestFlight admin panel are blank! They just giving device info and "uptimemillis: null"

I tried pulling log from "console" and here what I've got on app start: <files attached>





Yes, there are two applications that have same problem.

Fine, we've figured out what's caused problem. It was one of frameworks that we depend on.

How we figured it out?
There is "View device logs" button in Devices and simulators window (in Xcode). And its the only place where we've found some info about crash. So the log says that it couldn't find some framework, so we researched and found that there is some strange behavior, when you build from Xcode it runs ok, but when archived framework not attached to build so it caused crash. We updated that framework and everything works fine now.
