Start with the macOS 10.14.6 crash report and the Thread 0 stack, especially CGlobalConfig::~CGlobalConfig() during application exit. Reproduce closing WindTerm on the reported system and investigate the mutex-lock failure; done means the application exits without the uncaught std::__1::system_error crash.
