Test Studio Application Goes Unresponsive

I have recently moved my Test Studio application to a new laptop. For some reason Test Studio goes to "Not Responding" page grays out and does nothing. This happens simply opening the application, navigating the application, and when I try to run a test. Sometimes it will become responsive again after a few minutes and other time I have to force close. I have more than enough ram (8GB) and an equivalent processor (Intel Core i7 @ 2.2 GHz). Why is this happening?

Here is the error log when I try and run a test as well:
