I test on iOS, NetworkExtension and OpenVPNAdapter are worked well. My iOS device can connect remote server.
I don't know why MacOS is failed.
Should I used the system nextension on MacOS?

this error triggered by this file utun.hpp
If I called the library in container app and debug process as root, this error will not happened. But VPN client should call this library in app Network Extension, this error is really weird
I use openVPNAdapter to build MacOS VPN too, but print error "cannot open available utun device", Could you help me solve this error?
