SITL Crashing After Arming In X-Plane 12

I am trying to run a Heli SITL through mission planner and connect it to X-Plane (same PC). I believe I have the ports set up correctly. I can see that X-Plane is reporting that it is connected and sending and receiving data. I am using the x-plane heli model in mission planner as well. I can get as far as connecting the SITL but as soon as I arm it the SITL crashes.

I can’t figure out what is causing the crash. Any ideas what could be causing the issue or suggestions for trouble shooting would be appreciated.

Thank you
