Dragon stops listening? doesnt do commands? latest version of Dragon

I installed yesterday the latest version of Dragon, when I’m using commands, after 5 to 10 minutes, the Dragon stops doing my commands and dictation, I have to manually close the microphone ( red icon) and open again (green Icon) . It’s very frustrating. What can be the issue?

(Shut down Dragon and VoiceComputer, restart Dragon and create a new user profile)

If this doesn’t work, you’ll have to uninstall/reinstall Dragon.
