Did it happen after upgrade to Windows 11?

Have helped a friend of mine during the last year, setting up switches and lights. He’s on Windows and suddenly he was not able to open the Old WEB App (.html file not found) nor properly log into Phoscon. Password reset refused to accept the new password. We tried uninstalling/reinstalling to no avail and when I finally laid a hand on the machine myself, I noticed it was updated to Windows 11.
No matter what I tried I could not get it to work.
Ended up installing Ubuntu 22.04 LTS on VMware Player and that worked fine (except for no Phoscon light control sliders in Chrome, FireFox was OK.)
Any others seen this on Windows 11?
