Sorry to hear you are unable to open Sketch file in XD. Would you mind telling us if it's happening with a specific file or all the files? Is it possible for you to share the Sketch file with us over a private message so that we can check at our end? You may upload the file to a shared location such as Creative Cloud or Dropbox and share the url with us over a private message.
We will try our best to help.
Note: Please add the url of the post over a PM for reference.
Sorry for the delay in response and thanks for sharing the file. I am able to open this file at my end. Could you please try signing out of XD, Creative Cloud, restart the machine and then sign back in?
