Make 2d not working for rhino7

I recently upgraded to rhino 7 from rhino 6 and the make 2d command does not seem to be working. I have a fairly simple model built so I am not too sure why this is happening. Can anyone help?

Hi - In a quick test, that seems to work fine here on Rhino 7 on Mac.
What happens if you try it with a new file and just a simple box?
Also, please run the Rhino SystemInfo command and copy-paste the result here.
