Can uWebSockets-related objects be created and run in a child thread? Why does executing this->webApp = new uWS::App(); in std::thread detach mode cause an exception?

Yes it can be run in another thread but if so, you cannot call any method from other threads. The only thread safe function is Loop::defer which is like io_context::dispatch in asio. See read more
