Illustrator 2020 issues duplicating artboard

[AstronautLasso]

Illustrator seems to be having difficulty duplicating artboards with "Move/Copy Artwork with Artboard" selected while using Alt+dragging the target artboard. This issue only arose after upgrading to Illustrator 2020. I made sure scratch disks were set up properly, so I doubt this is a hardware issue. Is anyone else experiencing this? Any advice would be greatly appreciated!

Just here to say, I had the same problem. And the solutions provided here didn't really help. Eventually I figured out, in my case, it was because I had a clipping mask in the artboard I tried to duplicate. Once I released the clipping mask, it worked with no problem.
