Quitting program prompts Mac OS crash report

[astraylife]

This has been happening for several updates at least, but whenever I quit the game on my Mac I get a crash log. I'm not tech savvy so I don't know how much of the entire long log is useful but here is part of what it says:

 

Application Specific Information:
abort() called
terminating with uncaught exception of type std::__1::system_error: mutex lock failed: Invalid argument

I can provide more if that is helpful. The game runs fine, but every time I quit I get the same crash report.
