Can't start miracast from settings in Win11

I can't find my displays (Chromecast and Amazon Firestick) on the cast menu, while on other pcs with win 10 they're reachable; I upgraded my pc to win11 as soon as I bought it so I don't know if from this pc I could've casted in Win10. I tried to add them from wireless display settings and even there I couldn't find them; but if I cast from Edge or Chrome, i can cast the tab I'm browsing or even my full screen. DxDiag tells me that Miracast is available with HDCP.
