TeamViewer opens a strange window when application is closed

jhulala

When I close the TeamViewer application, a strange window is opened:

My Windows 10 Pro is installed on C drive, but my Users folders are on D drive. User profile name is "Remote User" and so its User Home directory is "D:\Users\Remote User".

I am not sure if this is relevant, but I assume it is. What TeamViewer tries to open when the application is closed? How can be this fixed? Please advise. Thanks.
