Blender Version
Broken: version: 2.90.1, branch: master, commit date: 2020-09-23 06:43, hash: rB3e85bb34d0d7
I'm not using any addon, this a fresh Blender Install with no customization whatsoever except for one keyboard remap because "~" is not easily accessible on a french keyboard.

Worked: N/A (2.90.1 is the 1st version of Blender where I tried the feature)

Short description of error
When I enable Optix denoiser, Blender crashes when rendering a simple scene (Cycles renderer using GPU compute)
This happens even with a default scene and (only a cube).
Note : Blender also crashes instantly when enabling Optix for viewport.

Exact steps for others to reproduce the error
-Enable Optix denoiser for rendering
-Press F12 to do a render
