Recently, only in the last few weeks, Ctrl+D started behaving erratically. I don’t know what changed. I didn’t upgrade Unreal Engine. But now when I use Ctrl+D to duplicate a blueprint node, it only works sometimes. It’s seemingly random. It’ll work one second and then stop, and then work again (without leaving the editor or BP). It either works or it deselects what’s selected and does nothing else. I tried closing other programs but haven’t been able to narrow it down to anything. What could be happening here? Could this be a problem with CommonUI? I’ve noticed other editor UI issues after enabling Common UI. (Win 10, Unreal 5.4.4)

Sorry to necro a year old post, but I was having this issue down to the letter. It’s an issue I’ve had in other programs too. In my case, it was another program running that I use for uni writing called Texmaker (for LaTeX). It messes with Ctrl commands, mainly copy, paste and duplicate in any other application I am using at the time.
Another software that can do this is Samsung Magician, but that usually doesn’t cause sporadic behaviour like this, its very consistent in not working if Samsung magician caused it. I’m not 100% sure of how the interaction works, but it is caused by another application consuming inputs when it shouldn’t. They could be continually attempting to get input focus, so sometimes it works and other times not.
