It's surpising how an OS system setting can affect the app interactions. I had been suffering this issue with copy paste in XD even within the same file. The app would just stop responding if I tried to copy paste text or objects. I had been suspecting the Surface Book 2 GPU issue but the problem persisted even after Microsoft released the fix to the GPU issue. It was sheer serendipity that I came across your solution to this insufferable issue. Thanks a ton.
