After installed Monterey 12.0.1 on my MacBook Pro (15 inch, 2016 2.0 GHz Quad-Core Intel i7), Messages simply will not open. When I click on the icon, nothing happens for a few seconds until the crash report appears. I've restarted my system and that hasn't helped. Is there an easy fix?

From Finder>Application>Messages.app

Quit Terminal.app
Quit Messages and try launching it normally.
