MacOS host networking stops when Parallels app launched

I searched the forum and my issue appears to be different than the other Big Sur networking problems that have been noted. When I launch the Parallels App on my Mac Mini the host computer's networking stops. I am not able to reach devices on my LAN or the Internet. This happens even if no virtual machines are running. When I shut down Parallels all returns to normal. I am using the latest Parallels version 16.1.3-49160. The problem started after upgrading the Mac to Big Sur. There were no issues using this version of Parallels with Catalina.

 

Hello, did you check it with Bridged and Shared network modes?
