Scratch that, did the repair and a clean install of drivers, same problem. Will try some other solutions from online in the meantime. Any other suggestions? The bug itself is happening now consistently when talking to the sloth demon at the end of the fade in the Broken Circle questline.
Tried any of the solutions here? https://forum.bioware.com/topic/95820-the-sloth-demon-is-difficult-enough-to-beat/page-2
Main one seems to be disable autosave, load to a save before the sloth demon, and then play through, turning autosave back on after.
There are some other fixes though, revolving round changing different graphics settings, try them too.
