I've arrived here because I've also got this problem. But mine started only this week (14 August 2023) which is a year and a half since the OP. I keep my Wndows 11 up to date so it isn't simply that I've caught up with him. Any ideas? I'm running on a Dell 7420 with Windows 11 Pro up to date. Alternatively, if alt-space is now off limits, what are people using as alternative hotkey?
