From the crash call stack, the app crashed at the line `windows_socket = nullptr;` This is because the previous line `windows_socket_.Close();` has already released all unmanaged resources associated with the StreamSocket object.

By RAII, assigning `windows_socket_` to nullptr is equivalent to calling `delete` on the StreamSocket allocated on the heap again, which results in null pointer exception `Exception infoEXCEPTION_ACCESS_VIOLATION_READ @0x00000000` because it has already been released in the previous line by Close().
