I receive error below during the startup of my 3rd VM. The first and second vm are ok. I reinstall Fusion 12 and recreated the vm and still having the same issue. No network connection after the 2nd VM. What is interesting, it start giving the error after the upgrade to Fusion Pro 12.2.1 "Could not connect 'Ethernet0' to virtual network '/dev/vmnet0". Any ideas? iMac 27-inch, 2019, OS Big Sur Version 11.6, Professional Version 12.2.1 (18811640)
