Can you look at the menu Extras > Options > Advanced > Advanced settings for connections to this computer: Access Control = Full Access.
Also please consider the answer of Christoph on this related post about connection problem on Windows 10 S mode.
Another option is (if possible) to use the Quick Support app to the remote computer to connect.
I think this will lead you to end with this issue.
I didn't get an answer I could use but I did resolve the issue. The Windows Home S mode was blocking me from downloading the App. When I went to the Google App Store, as directed, that is the version taht didn't work. I turned off the S mode, uninstalled the Google App and download/re-installed Teamviewer from the internet and everything worked as expected.
Apparently there is somethng wrong with the Google App version. At any rate, everything is working fine now.
Thank you, Norm W.
