I also recently changed to Windows 11 from 10 and now I've had it where the control panel won't open until I reboot, and now today it opened fine when I started my PC and played some BF2042 then WHDarktide, but now the control panel won't close. I left it on the Metrics screen while playing the games.
Version 24.12.1, Radeon 6950XT. Win11 24H2.
