Since Monterey 12.3 update, Internet Sharing through Ethernet adapter to Windows PC results in Unidentified Network, No internet access.
I have been using a USB-C Ethernet adapter with my MacBook Pro to share internet to my Windows PC to it's Ethernet port. This has worked near flawlessly ever since I started doing this.
I installed the macOS 12.3 update last night and now when I try Internet Sharing it shows up as Unidentified network, No internet access on my Windows PC's Ethernet adapter. Its Wifi adapter works just fine. Internet Sharing is on sharing my connection from Wifi over Ethernet Adapter (en4) which I have always used.
Running ipconfig /renew gives an error message : An error occurred while renewing interface Ethernet : unable to contact your DCHP server. Request has timed out.
I have tried running the other ipconfig and similar commands found on the internet but no luck.
