Big Sur won't let me log into Messages

[aevan]

I did a clean install of Big Sur, and even though I had no problems with Messages on the beta, now it's just stuck at the Sign in screen (I entered my iCloud credentials and it's just showing the little loading animation). In some attempts I also get an error message. I let it try to log in for hours, and it's still at the same screen.

I tried several things, from restarting to logging in and out of Face Time (which someone suggested to me), but nothing.


Anyone has any ideas?

well, it's some kind of block by apple. You have to call to support...
