But bugs are still present there and you may notice theWindows 11 start menu not working.

Relaunching Windows Explorer or reboot your system is very effective to fix the problem.

Lets first reboot your machine to see if the problem is fixed.

Remove any third-party utility or malicious app if the start menu wont open or not respond after installing it.

If the above solutions didnt help, they tryupdate or reinstall the graphics driveron your box.
