iMessage signs out as soon as I sign in. Big Sur

I tried generating new serials multiple times and followed the Opencore post install troubleshooting as well. However I still can't get iMessage to work for some reason.

When I type in the correct login for I message, it shows the main iMessage dialogue for a second, and then quits and goes back into the login screen.

If anyone could help it would be greatly appreciated!
