I updated to Big Sur today and now iMessage doesn't work. After signing in, I keep getting this the error message "unknown error occurred". iMessage preferences windows does not open. iMessage is also not listed under the services using my iCloud account. I re-installed macOS Big Sur and it did not resolve my issue. I've even restarted my Mac several time and this issue does not resolve

Hi Eric~F,
Appreciate your response. I've tried all of the trouble shooting items on the page you suggested and unfortunately not 1 of them worked to resolve the issue.
What's next?
