I then rebooted my Win11 VM with 'Shared' still enabled - no internet on boot up. Interesting thing, when I switched back to 'shared' internet died after it started working with the hot switch to 'default'. Plus that got done when I updated to Win11 last week.

They also wanted me to reinstall tools, as if I haven't tried that (I been around since v7 of Parallels). I just can't be living with a IP that I'd be getting from the DHCP server that my MacBook is connected to, I need the shared IP from Parallels Host, full stop! They had me change to 'default' network but that won't work for me as I need 'Shared' but I did that 'tip' and internet came back without restarting anything. The customer support people are running me around in circles. I hope Parallels tech pop in and follow up. I think something bad is lurking in this new Parallels 18.0.2. Internet still operational on Oracle Linux Server and Win10 (non-ARM). I then shut them both down and then MacBook and started everything back up fresh (cause, why not?). Started up Win10 (non-ARM) internet restored. I started Oracle Linux Server first, internet restored. I shut down both VMs and restarted Parallels Pro 18.0.2. I then checked my Oracle Linux Server, it also lost internet. I restarted Win10, this did not restore internet. Moments ago before visiting this thread internet started to come and go on my Win10 (non-ARM).

I don't recall this problem ever happening before - having to restart Parallels application after shutting down VMs to restore internet. I've been a Parallels users since Desktop 7, 2012. I updated to Parallels Pro 18.0.2 from Parallels (standard) 17 on Saturday Sept 18th. I believe this problem just happened to me.
