Rhino 5 - Rendered view mode shows objects as opaque black - Rhino

I recently redownloaded and installed Rhino 5 on my PC. When I hit rendered view mode in perspective, all objects show up as opaque black. When I select them and uncheck “Casts shadows” or “Receives shadows”, the objects show different shaded surfaces (so they don’t appear black anymore), but then they don’t show any shadows ofc since it’s turned off. Note that when the command “Render” is run, the shadows do render via the Rhino renderer. OpenGL version Im running is 4.6 Rhino version 5
