I just installed windows 11 N LTSC. All's been stable for me since. No crash. The fact is that updating an operating system the way Microsoft does is not at all suitable for production environments where stability and control are paramount. So many things can go wrong with updates, as they have proven several times. That's why they have these LTSC versions of windows available.
They just sent out there and copied the mobile OS models of update and feature additions as if a mobile device and a PC were used in the same way.

An update of sorts:
We are in communication with Microsoft, and they have identified a problem in dxgmm2.sys and have a fix in the works, but have yet to supply a date/KB. We'll update here once we know more.
Thanks for your patience.

There's hope. Thanks Sidefx.

I have the same issue on the other machine with the 3080. Im done.

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

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.

Since we're on a Sidefx forum, I guess the closest party with technical insight that could hear us out and look into it is Sidefx. Eventually they may talk to nvidia and/or Microsoft
