Apple Intelligence is now available on iPhone, iPad, and Mac!
Every time I open Messages I get the following message:
"There was a problem with Messages. You need to quit and open Messages again."
If I try two or three times Messages will finally open and works fine until I close it again.
How do I fix this?
MacBook Pro 13", macOS 10.14
The first thing you could try is booting in Safe Mode, when starting hold down the shift key. It takes a little long to get to the login screen but just wait and when at desktop give it a minute then close down, this process carries out some general housekeeping that may sort out certain issues.

If that fails you could try signing out of Messages, Restart and then sign back in, this discussion explains how.
