The one in the screenshot is: https://www.thingiverse.com/thing:2432066
I have also had issues with https://www.printables.com/model/610425-voyager-intrepid-class and https://www.printables.com/model/602688-enterprise-e-sovereign-class
With the final two, if I restart my computer it would get the first slice, but if I tried to change something it would never slice again, even if I reversed those changes until I restarted the computer.
Less issues, but still slow, with 5.5
