Instead of doing Dynamic Link, try importing your Premiere Pro project into AE using the Import Premiere Pro Project command and working with it that way. Does Color Finesse still hang?
Just import a piece of footage by itself into a brand new project and try. Does it still hang?
And try it on a comp with no footage, just a solid layer, in a brand new project and try. Does it still hang?
This isn't a known issue. I tried a quick test and everything worked as expected, but there are a lot of variables there so I may just not have duplicated your exact scenario.
If you could send us a sample project that shows the problem we'd be happy to take a look and see what we can find.
I agree with Szalam's suggestions and things to try.
I'm having the same issue. I reconstructed my timeline in AE from scratch, and as long as nothing in the project file has Warp Stabilizer on it, it seems to work fine. As soon as Warp Stabilizer (and sometimes even Rolling Shutter Repair) is applied anywhere in the project, it becomes iffy. The most consistent failure (and by that, I mean 100%) is when Warp Stabilizer is processing in the background in the same comp. When all the calculations are done, it only hangs for me about 20% of the time.
There are some known issues with Dynamic Link, Warp Stabilizer, and other things like that in 13.5. The update coming out should fix that. It's supposed to be here in a week or less.
I'm running 13.5.1 and still having the same problem.
After Effects hangs on launching Color Finesse (Full Interface).
Really need to get this resolved - my color correction workflow depends on Color Finesse.
Since updating to After Effects 2015 I have had numerous issues.
I want to roll back to 2014 but in the Previous Versions option on Creative Cloud I am not giving the option to roll back to After Effects 2014.

As Szalam says, there is a Color Finesse 3.0.14 update now available on our website that fixes a crash launching the UI when Color Finesse has been applied to multiple adjustment layers, or when used via Dynamic Link.
There have been a number of different issues which manifest themselves as "UI won't launch" that all have different root causes. AE 13.5 has some issues with Dynamic Link and Warp Stabilizer; Color Finesse had an issue with multiple adjustment layers/Dynamic Link; OS X prior to 10.10.4 had memory allocation issues which could (rarely) cause the UI not to launch.
This thread seems to contain a mix of these issues, all of which have separate causes/fixes, making it a bit hard to make sense of.
Thanks Szalam this update has helped a lot.
