Yes, I have this bug too. Support hasn't been very helpful other than telling me to "wait for a fix" for nearly 9 days now -- after the community manager didn't bother to read my ticket until a higher GM got involved (telling me to repair/reinstall the game after already saying I did so and it is NOT a files problem, but a CHARACTER problem with video evidence to show).
It's something to do with the G21 ending. Any dialogue box will cause that character to have the game crash. Any other character works completely fine.
This is my experience after coming back to the game after a few years hiatus. Didn't even get to play the game for two days and now my character I've had since day 1 is still completely broken and the game is unplayable.
Edit: Spelling
Same havent really really played since this update and im loving it but now I can't do anything with my main because of this MAJOR BUG. We shouldn't be waiting over a week for such a giant BUG this should of been patched already.
@Nexon Please get this done already and the people who are experiencing this issue should get a major compensation I mean I can't do anything right now at all because of this I can lvl but cant talk to any NPC or rebirth. Right now I would of already had 6 more warrior seals for grandmaster warrior at this time. -_-
