Stuck on “Downloading H3 Face Refiner model files” in WanGP in Stability Matrix?

I’ve been using MiniMax H3 in WanGP which recently added support for a H3 Face Refiner. When trying to use the face refiner, it seems to get stuck on the “downloading h3 face refiner model files” stage. I can see network activity for a period of time (which makes sense if it was actively downloading) but the network activity eventually stops - but it never moves past the “downloading h3 face refiner…” stage within WanGP. I see the files in the Buffalo_l folder it created, so I’m not sure what is causing the hang up. Using stability Matrix so the console doesn’t provide any details. Anybody run into anything similar or have an idea?
