Can't stop IPR or close the IPR window

Hi there. An old thread but I'm having exactly this issue with Vray GPU IPR. I'm using Tyflow in my scene. I have a 4090 GPU. The IPR just sits there after I press stop and will not stop and makes 3dsmax unresponsive.

4090GPU

AMD threadripper CPU

256gb RAM.

VrayGPU6 Update 2

To add...it's only when I'm using RTX. CUDA does not do this.

I have the latest NVIDIA drivers.

This happens even if you disable the TyFlow? Sometimes it seems to want to calculate after a render, and if you are way down the timeline it could be slow. Sometimes TyFlow doesn’t display its progress indicator in the bottom left.
