If you can somehow transfer the project to Blender and meet your deadline, maybe do it and come back later. I'll also go back and try other things when I finish with this render

Mine has not crashed even once since I switched back to win10 22H2 Build 19045.6456, Houdini 21.0.596 and Nvidia Studio driver 577.00

If you're thinking of downgrading to Windows 10, or going back to older RTX series, be careful. I'm on Windows 10 (Extended Security Updates), with RTX 3060 cards, and I have this issue as well. Since mid-January, when my system received update KB5073724. What's worse, Windows Update doesn't allow me to remove it.

If its really an issue with Windows then GPU rendering with Cycles would produce errors as well, wouldn't it? If it doesnt, what does XPU Karma differently? If it does I can as well render on CPU in Houdini.

Edit: I can not find any reports on crashes during GPU rending in Blender related to the Windows update.
