I did try in another account which is also an Admin account. Messages opened fine, but only showed chats up to February of this year, and did not update to current time. I did make sure I was signed in to Messages.I only have the one account so am sure it was the right one.
If I boot in Safe Mode Messages opens and stays open. If I am super fast and can click to. choose another message from the one my son sent me which seems to have caused the crash, Messages stays open. My son sent me 3videos he had taken with his iPhone and after that is when Messages just began crashing and giving the CoreAudio error.
