<unknown> as trace on error

Hello !

I produce a 2d game and some of my players have crashs. I added sentry and give this version to concerned plays to be able to know more about crash. But, where a fake crash produce this trace in sentry:

OS Version: Linux 5.4.0-56-generic (None)
Report Version: 104

My player crash produce this trace:

3   <unknown>                       0x7ff7b5dcb7bb      <unknown>

So i don't know where is this .unwrap... Why these unknowns ? And, how can i know more about my player crash (they are simple user which cannot debug or make difficults operations) ?

Note: I'm a newbie in Rust or compiled programs :slight_smile:
