Lag and Illustrator "Not Responding" after copy command
The platform is: Illustrator 23.0.6 64-bit, on Win10 Enterprise 1903 latest updates, and with nVidia drivers R430 U5 (431.70).
The bug is that Illustrator freezes for ~5 seconds after/during a simple copy command, and "Not Responding" is displayed on the top title bar. This can be induced by just opening a new file, drawing a rectangle, then trying to copy it (with Ctrl-C or with the menu command).
This is destroying my workflow...
This certainly is not a normal behaviour of Illustrator.

I did as you asked and emailed that address and never got a reply...
