Unfortunately, app has stopped showing only if logcat isn't active

Question

I've an app which if it is only running on emulator (without Android Studio running logcat), shows that error.

But if I try to get the stack trace with logcat, (by running the emulator along Android Studio and Logcat) everything works fine, I've already tested it by either just running the emulator and ordering the app to run on emulator. I could try debugging the app but I don't think this would help in any way.

What am I supposed to consider of this difference in behavior? Would there be an error in the app or not?
