Audio Engine Technical Issue

Help!
I was working on a score just now and Dorico seemed to lock up. I shut the program down and have tried to reopen Dirico but am getting the attached message and when I click "Terminate I get a message that says the program can not connect to the Audio Engine.

What to do??
Thanks.

The quickest way to get back up and running would be to restart your computer, then run Dorico again.

I will try that.
Thanks.

That worked.
Thank you!
