This error is still applicable in 12.0.1, but we have a workaround.

Upon investigation, we noticed that the "com.apple.Virtualization.Installation" process is crashing in its "com.apple.cfnetwork.cfnetworkagentclient" thread.

Workaround: Uncheck Automatic Proxy Configuration in the proxy tab of network preferences.

We noticed that another thread of the crashing process was "com.apple.libnetwork.pacResolution" which lead us to disabling proxies and finding that this "fixed it."

Since it's a bug in Apple's code, I will close this issue.
