Have you tried going to camp using the "camp" button on the Waypoints panel on the right side of the map, rather than the "end the day" button? Because it won't let me use the "end the day" button when I have a dead party member but I can always travel to camp using the map.
I only know of one way to go to camp, and that is in the upper right attached to the map, says "end day go to camp" Either way I got out of there, had to reload a few times inorder to get the fallen companions names to appear so I could raise them, once raised, I was able to leave
