glfwCreateWindow crashes in separate thread which also called glfwInit

On macOS you cannot do this from thread. Read this comment: Multithreading GLFW? - #5 by elmindreda

Cocoa has an event queue per thread that can only be accessed from that thread, but the main thread event queue is the one that receives window and input events, and most window and view operations may only be performed on the main thread.

So you need to do window creation and event processing on main thread.
