[Cura 5.6 is slicing slow]

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

[Cura 5.6 is slicing slow]

Not only is slicing slower, but I have objects that just won't slice no matter what. It just gives me a "Slicing failed with an unexpected error. Please consider reporting a bug on our issue tracker." message. Reporting the bug requires a GitHub login, which I don't have. 

 

For some, disabling tree supports and using normal supports work. For others, it just won't go no matter what settings I'm using. I get a massive spike in CPU usage just before the slice crashes. 

[Ultistik Powder-Coated PEI Bed Upgrade - Review]

Is there a reason why it needs to be installed on the glass or can it be installed directly onto the metal plate? Is the concern the direct heat or the Z offset?
