Your partner's desktop is no longer accessible

When I have remoted into a friends laptop and they launch a program that prompts them with "Do you want to allow this App to make changes to your device", I get a pop-up window right in the middle of my screen that says "Your partner's desktop is no longer accessible".

When my friend responds to their prompt with "Yes", I would have expected my pop-up window to go away, but it doesn't.  It stays in the middle ov my screen.   I appear to be able to control the mouse on my friend's computer, but this pop-up window on my screen is the issue.  How do I get rid of this pop-up message?  I previously remoted into my friend's other laptop and performed the same activities and I did not encounter this pop-up windows.  Is there a setting that is not configured properly when accessing one of his laptops?
