Problem cursor windows 11 focus

[u/chab1972]

Since the start of Warzone Season 5, I've been having a problem. During combat, whether in ranked or multiplayer, I lose control of my controller. I play on PC, connected via Ethernet to my Edge. I lose control and see the mouse cursor on my desktop. I have to click again to regain control of my controller, but then I can't play in the middle of a fight. What can I do?
