PT 11 Initializing Audio Engine Restarts Computer

I Just got the Eleven rack and installed PT 10.3.9 and PT 11. PT 11 worked fine for a few days. I didnt install anything after that or did any system changes. PT 10.3.9 works fine but now when I run PT 11 it loads up until it gets to Initializing Audio Engine then my computer shuts down and restarts. I tried it with the Eleven rack connected and disconnected and the same issue exists.



I am running an iMac i3 12GB RAM.
