If you look at the last post by morticusrayzr he managed to get past that cutscene on a different computer.
I have seen some computers have issues with the KOTET cutscenes too and most appear to use intel video cards , unfortunately that appears to be a known issue with the intel video driver as listed in the release notes
- Intermittent crashes or hangs may occur in Tom Clancy's The Division™ (DX12*), The Guild 3*, and other games.
Swtor appears to be one of the other games in that instance, but i do not know if it is related to the darth zhorrid convo as that is part of the original story and kotet hang appeared after its release.
I think they are running around the 5 - 7 day mark at present with tickets, this is on the long end unfortunately the ideal time is 1 - 3 day point usually.
