Mine is less than a year old so I wouldn't go that route. I'm still having the issue, but I did manage to the end of Shadowbringers. Crashed on Seat of Sacrifice and THREE reinstalls haven't helped. I noticed one of the tomestone icons was missing from the duty finder, and on one of the earlier ones, some dialogue was missing from a cutscene yesterday (which prompted the first reinstall.) There's some kind of corruption going on causing it.
