The Start menu and the Win key in Windows 11 sometimes fail to open

While using Windows 11, the Start menu and the Windows logo key on the keyboard suddenly stop working completely; neither clicking nor pressing them produces any response. I have tried the following steps, but none of them worked:

Pressing Fn + Win to confirm that the Win key lock is not enabled

Restarting the Explorer process

Running the system file check with `sfc /scannow`

Currently, only restarting the computer temporarily restores normal functionality, but the issue reoccurs after the system has been running for a while. Please advise on possible causes and solutions.
