Windows 10: Facebook login problem with Win 11

Just built a new PC i3-8350, 1 TB HDD, 32 GB DDR4 2400, Gigabyte B360M-DS3H; I am unable to login to Facebook since I upgraded to Win 11, it is not recognizing my username message: "The email or mobile number you entered isn't connected to an account.". I do not have this problem on any of my Win 10 PCs and also used Win 11 trial version on another PC with no Facebook problems. I have the same problem with multiple browsers Chrome, Edge, Firefox, Opera and Brave. Problem seems to pertain to this PC only.
