FATAL 11, how to troubleshoot?

Hi, I’m getting a FATAL 11 crash on my Android game about 1 out of 15 games. I got one logged with ADB Logcat this time but I have no idea how to troubleshoot it. Here’s the text in case anyone has ideas? Thanks in advance.

the issue is most likely in native code parts, so if you have any native code plugins, I would check those first. It can also be a Unity bug or device driver related error.

Thank you for the response. The only native code plugins I’m using are the 3 ad systems. None of those should have been doing anything when the crash occurred (during game play, not any time ads are displayed). How would I “check them”? Also, if it was a Unity bug, how would it be troubleshooted? AFAIK, I can only send bug reports to Unity from inside the Unity editor.
