Short description of error
Hello, I am having an error in Blender 2.90.1 when I use cycles and I have selected the CPU device and I activate noise reduction in the viewer by activating Automatic or Optix, the program closes. It doesn't close if I have OpenImageDenoise enabled.

I always use GPU as a device, but sometimes it can happen that we have selected CPU by default and activate that box, with which our project if it was not saved can disappear, greetings

Exact steps for others to reproduce the error

I have to clarify that I know perfectly well that Optix is used only with nvidia graphics, therefore it should not appear when a CPU device is selected, it should disappear so that the crash does not occur.
