While in Beta I could progress at this stage if I stood around and waited for 5 minutes, Freya dies and then the dialogue allows you to progress.
No idea if it will work for you, perhaps worth a try though?
Problems with companion quest progress are known though, you can put in a bug report if you continue to experience the bug. If you do, once you’ve filled out the template, select it all, copy and paste into a New Topic.
