Broken: version: 2.90.1, branch: master, commit date: 2020-09-23 06:43, hash: rB3e85bb34d0d7
Worked: (newest version of Blender that worked as expected)

Short description of error
Good Day, I have updated Blender to 2.90.1 earlier this week and opened this version today for the first time.
When I clicked on Rendered shading in the Viewport Blender imediatly crashed.
After looking at some settings if something was out of place I tried the Denoising Viewport feature which appertantly is the culprit.

However, the OpenImageDenoise does not cause a crash. Only Automatic and OptiX do.
This is not a severe bug as im fine with disabling the Denoiser for now. But it would be nice to have that working :D

Exact steps for others to reproduce the error
Use Cylces as Engine -> Enable Viewport Denoising (either Automatic or OptiX) -> Click on Rendered Viewport Shading -> Blender crashes.

I have attached a screencapture video of me demonstrating the issue.

Thanks in advance and have a nice day!

Best regards,

Jordi
