The ability to connect to a wireless display stopped working with the version previous to 1.36 (About a month ago). I waited to see if Windows or Start 11 Updates fixed the issue but they did not. . The fly-out window that allows you to select the wireless display target open very briefly (Milliseconds) then disappears before you can do anything with it. This also happens with the settings fly-out from the taskbar. Works good without Start 11 loaded but fails with start 11. The was not a problem until recently and it affects function on two separate computers. Currently running Start 11 Version 1.36 on two separate machines with Windows 11 Pro 22H2 OS Build 22621.963
Hi Isosynchronous,
So far I cannot recreate your issue with the same versions, when I press Win-K it opens the dispay

One thing I wanted to double-check, you said the settings flyout is also not working for you. Are you talking about this:

Seems like it could be a conflict with another program you have running, it might be best to go through a clean boot and see if it still functions the same or not.
