Unknown Error. Messages MacBook Sign-In

I continue to be unable to sign into Messages on my Macbook Pro. I'm on Monterey 12.6.3. This has been going on for months. I know the username and password are correct. It doesn't matter what Wi-Fi I'm connected to or if I tether to my phone. No error code or anything aside from "Unknown Error." I tried restarting my computer with no change.

MacBook Pro 15″, macOS 12.5
