That simply sounds like a keyboard issue. Check your configuration and in particular any external tools that may remap system-wide shortcuts like instant messengers, screenshot tools, customizabble mouse buttons, gaming keyboard tools and so on.
I am currently attempting to use Ray-Traced 3D function for extruding text.
Well, you shouldn't. It's considered an Obsolete Feature in recent versions of AE. You should be using C4D Lite, which is better. But Mylenium is almost surely correct in his diagnosis. So read his words carefully.
I have swapped keyboards and mouse, none have any programmable buttons or anything. I have tried it on my second rig and I still run into the same issue. Both rigs don't have any third-party apps like instant messenger. All they have on them is Adobe products and stock footage.
what's your exact Ae version? note that CC2017 comes with the much better replacement the Cinema4D Renderer. it is faster, and works on the CPU, not GPU. try to narrow down your problem. one comp, one element. if it still persists, upload the project file - we can take a look what's going on there. screenshots would be helpful tool
