I can confirm that the engine is active on Windows (at least after installing the Framework driver bundle and the AMD adrenaline drivers). You can see the AMD IPU device under System Devices in Device Manager)
That said, Windows Studio Effects (which is the only functionality in Windows which uses a local AI processor) is not present. From searching a bit, I think there needs to be some additional AMD drivers provided (perhaps MEP enumerator) which seem to not be there.
I haven’t tried the development demo from AMD yet. Perhaps that works.
