I hit this problem as well. VMware NAT Service runs somewhere between 18 and 30% of my host's CPU all the time -- even when both guest and host are completely idle. Additionally, guests lost DNS through NAT service, and I had to add manual DNS servers to all guests. Host and guest are Win 11 22H2, fully patched. I'd really rather not downgrade. Hopefully 17.5.1 comes quickly and patches this?
