Either your code or a third-party library you are using is manually spinning the runloop. This is causing -workspaceDidEndTransaction: to be called re-entrantly and triggers a use after free. If you set a breakpoint on -[NSRunLoop runMode:beforeDate:] and -[NSRunLoop runUntilDate:], it should hit with the guilty code being on the previous stack frame.

While manually spinning the run loop is never recommended, if you can delay doing it until your application finishes starting up (all the launch app delegate calls received) you should avoid hitting this crash.
