Hello, I am using Archicad 23 and trying to simply copy Ctrl+C a door in my model. I am using windows 10 and there is a windows error sound eveytime I copy it. I tried copy the stair and it was fine. I am very confused why
You cannot copy door or window, as it's part of the wall. What you can do - use drag a copy command to make door copy in the same wall or use pipette (shortcut Alt) to pick up parameters from already created door - then new door will have these parameters, or you can inject picked up parameters into another door (syringe to Alt Ctrl).
