When setting XPU view screen at the dropdown menu the whole PC is crashing and restarts. This happen also when rendering in few set ups. I'm running Houdini 21.0.0559 on MSI GT75 Titan SF8 64Vram with Nvidia RTX 2070 latest version update 591.74.
Anyone know how what causing that and how it can be fixed?
Found on Youtube video dealing with similar issue which fixed it with Houdini.env adding that line: KARMA_XPU_OPTIX_ENABLE_OPTIXIR=1
Attached here, but it doesn't seem to work.

“unload the windows latest update (20160114) can fix it, Microsoft's full responsibility!”

This sounds like no solution.
Windows can't unload as already passed more than 10 days, and since the last update there was another. Not sure it is the best idea to stay with previous Win11 versions as it might be vulnerable and Microsoft will continuosly annoying to update.
I hope this will be fixed by SideFX with next daily build versions.
Or if anyone has some other idea how to fix that, it will great.

So consulting ChatGPT master Houdini I think we managed to solve it.
Mainly his suggestions:
Disable Hardware-Accelerated GPU Scheduling, it can cause hard reboots with XPU.
add line to .env file: KARMA_XPU_DISABLE_CPU = 1
