Dear Kusha!
At the current moment I have no problems with Dreamweaver's start. Below I described the steps, which went to the crash. They are simple and straightforward.
Using Creative Cloud
I've installed both the Dreamweaver and Photoshop apps (trial).
Now I start Dreamweaver, selecting appropriate item from system menu:
and get the issue.
By the way, Photoshop installed simultaneously with Dreamweaver works perfectly:

I don't understand what happened with the app, but it works.
Dear Kusha, excuse me for disturbance. I suppose, something worked wrong earlier, but now the error disappeared. How can I inform you, if the issue will be back in future?
