First, mine is really repeatable crash. I am at Druid grove vendor Aaron. for some reason, if I sell an item from my main gnome bard character, exit after and do a save, it always crash. Initially I thought it was random and tried selling just items from other companions and save afterwards. All worked fine. Did more save and still working but then just selling items for my main and click save crash the game still.
I was trying to run the game as admin but could not load/find the save game (maybe because I disabled cross save?).
Edited: I manage to run as admin and now my profile screw up and can't go back to my original profile. I can copy the save games and try but now profile is all screwed up

. Running as admin did squat and just broke my profile

This is the application error I got via Event viewer:
