Currently, Microsoft has responded to the BUG, while clarifying the reason for the bug, it gave a temporary repair method.

It is reported that the culprit of the BUG is Win11's IRIS service, which is suspected to be related to functions such as Windows focus, but Microsoft has never explicitly acknowledged it.

If you want to repair the bug, you need to use the administrator mode to open the command symbol (CMD), and then enter the command & nbsp;reg delete HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\IrisService /f && shutdown -r -t 0”。

The command will delete the registry value of the IRIS service to solve the problem.
