Is there a way to prevent iMessage from disconnecting on Mac Studio?

A few months ago (seems like one of the past MacOS updates) when I use iMessage on my Mac Studio it has logged out and forces me to re-log in. I do that and a day latter it has disconnected again. It is NOT my internet disconnecting!!!! I don't lose syncing for calendars or contacts or anything else, just iMessages. I can go to my iPad, or my iMac all connected to the same internet connection and everything else works except my Mac Studio. Again, this started happening a few months ago, seemingly when I did one of the last few MacOS updates, but I don't remember which. I am presently running 14.3.1 but its been doing this for a while now.

Thanks for any help.
