A couple people have reported a problem there.
Try going to the murder scene first (talk to Aureus in the legion headquarters and then head to the King Crab tavern).
That will trigger the same event, but without the dialogue, so it is possible it may work properly. If the problem is with the End of Time, though, you will get the same crash.
Please email supportdos@larian.com, with a description of the problem and the report.zip file generated by the
D:OS support tool (for the PC version). The zip will contain system info, crash dumps, and your saves (if file size is a problem, you may need to delete older saves from the zip), which should help Larian fix the problem.
