Bridged Networking Breaks Host Network Until Reboot

Sonoma 14.6.1, Parallels 19.4.1. M2 Mac mini wired and wifi; Ubiquiti Unified network. Windows 11 guest with latest parallels extensions.
Shared networking works.
When I choose any of the bridged network options, those work for the Windows 11 guest. Including ones for separate vlans. But as soon as I switch to that network, all network access on my hose Mac OS stops. Disabling (make inactive/active) the network adapter does not bring it back. Only thing that resolves it is a reboot. Any ideas?
