Messages is quiting

My damn Messages on my iMac Pro is still f’d up.  Works on iPhone and iPad just fine.  
You know I’ll follow your lead.  What would you do if you were me?

___________


Steps:

Log out of messages
Delete the attachments folder. You don’t actually have to delete it. Just move it onto the desktop.
location of attachments folder is as follows:
in Finder, go to “Go” in the menu bar and hold down option.
you’ll now see “Library”. Select it.
go to Messages
move or delete the “attachments” folder

While in the hidden library folder, go to Preferences folder
Throw away the file(s) titled something similar to com.apple.messages…. Or com.apple.imessage….
They will regenerate.

Start messages and log back in once again. Be sure once logged in, go to preferences for messages and check that both your phone number and email address(es) are all checked.

If these don’t solve the issue, you may want to move to Ventura. It’s in 13.0 right now so normally you wouldn’t want to upgrade until the .1 release.
But if it’s driving you crazy it may be worth it to you to risk the .0 release.
