D4 will not launch on Windows 11

D4 will no longer launch from Windows 11. Get system error saying I’m not on an updated OS, that I need Windows 10 or higher.
I can only get D4 to launch if I place Steam as Run as Admin, Battle.net Run as Admin, and then D4 Run as Admin, copy and place the .exe on the desktop.

The game used to work, but I haven’t played since October. Now, it just gives errors. Help

You should report this to the D4 team in the D4 forum. This one if for Bnet only.
