Hello, I am experiencing crash on TopShelf and I checked all the crashlogs, but I don't know how to interpret it.

I see only addresses in the trace logs, so it's really hard to understand what's going on. Is there a way how to symbolicate frames 5 - 17?

Does anybody have an idea, what can be wrong?

Thanks in advance.

Thank you for your response. I attached the file.

I can not reproduce the crash, this is crash report from users I found it in Organizer, so I apologize for partially symbolicated crash report.

Reading all the crash logs I noticed that crashed thread is always > 0

For this example, it's Thread 6
