I cannot get my illustrator to copy and paste. The newer the version, the more frequent this issue happens. Now, I couldn't even copy and paste.

I'm not using any 3rd party clipboard management. I did not reconfigure my keyboard shortcuts. I have cleared windows clipboard, cleared preference. I tried shutting off the software and reopen. Every time is still the same.

It's not a new issue. What baffles me is Adobe keep coming out to new features while couldn't deal with such simple function.
