Windows HVM + sys-whonix networking suddenly broken

Hello, after the most recent whonix gateway update my Windows 10 HVM’s internet suddenly stopped working. To be candid this could be a complete coincidence however the timing of the update with the sudden network unavailability seems suspicious.

I have an existing windows HVM that has the net and iface xen PV drivers manually installed directly (qubes windows tools not installed) that has its NetVM as sys-whonix.

Up until now it has worked perfectly fine, however suddenly after updating whonix-gateway all networking to the HVM is broken, showing “Unidentified network”.

I have since followed the qubes guide to setup a Static IP for a windows HVM to make sure everything was correct, but even with a static ip (correctly using the ip values from Qube Manager, and trying both /24 and /32 subnet prefix length) it still doesn’t work.

I even tried to install a brand new windows HVM following the same guide with a windows 10 enterprise ltsc iso, and the exact same issue occurred. The brand new HVM does not have any xen PV drivers present unlike my existing windows HVM.

Any idea what could have changed?
