Nahimic Service:

Then typing in "msconfig" and pressing ok. From there I chose the services tab. Then on the bottom left I ticked the hide all Microsoft services so I didn't damage anything. And finally after a process of elimination I found that the Nahimic service caused my game to crash once loading in the open world. I also went to the startup tab on the same settings, and through task manager only had the essential programs startup. Here is a link to help anyone with trouble, it helped me figure this out, starting at Fix 9 (performing a clean boot).
