The fix for this issue is now available in the latest update 14.0.2 of InDesign 2019.
If you are unable to see the update notification yet, open the menu (three dots) from the top-right of Creative Cloud desktop application and click on ‘Check For App Updates’.
Once the update button is shown against InDesign, click on the button to update to Id 14.0.2.
If you face any problems with the new update, do let us know in the comments.
I have this same problem using Win 10, this solution doesn't help, I get the message that Ic 2019 "Cannot open CopyPlugin.vbs" file.
