The game keeps deadlocking/crashing once you switch some armor pieces in the inventory since dawn of ragnarök - a few clicks work, then the game just hangs up and you have to kill it via task manager.
The issue can be offset by a bit when closing the inventory after each change, but it will still crash after a few more armor piece changes.
Verifying files didn't help - neither did reinstalling.
It's probably the same issue as this one I guess:
