That is a different message than what these guys are getting, actually. The message the other guys are getting has more information in it, as it is a result of an exception being thrown by the speech component and caught by VA. What you are seeing is VA asking Windows to enumerate its available speech engines and Windows is saying it doesn't have any (the component did not raise an exception). This looks like a VA problem, but with v1.8.2, VA is now using .Net framework v4.7.2, and your system is now touching on components that probably have not been accessed before
now.
What do you have selected in the Options screen, System/Advanced tab for the speech engine? Did you install any speech engines or are you using the one built in?
If you are using the built-in speech engine, 'Use Built-in SAPI speech Engines' will be selected. Otherwise it will be, 'Use installed Speech Platform Speech Engines'.
In either case, an intermittent/random message like that is totally abnormal (this would be the first I've seen of that in over ten years) and is indicative of a system issue outside of VA's control. If you are using an installed speech engine, you'll want to try uninstalling and reinstalling BOTH the speech platform and the speech engine(s). If you are using the built-in speech engine, you'll want to try doing a system file scan (assuming Win10):
