Rhino crashes when opening render properties

Hello,

I’m new on this website and still learning how to use Rhino properly so I hope someone can help me. For some reason my rhino file crashes every time I try to change the color of the render background. This started happening out of nowhere and now it crashes every single time. I’m not sure what I did wrong but here are some photos of my problem.

I’m not sure what other information I need to provide but please let me know.

Hi - please run the Rhino SystemInfo command and copy-paste the result here.
Are you sending in the crash reports when the dialog box appears? Make sure to always do so and include your eMail address and a short description of what you were doing when it crashed.
