Hi,

 

Upgraded my Dell XPS 7390 to Windows 11 during beta and found the start menu not working so I switched back to Windows 10. Now with the full release of Windows 11, I have upgraded again and the start menu still does not work.

 

Windows log files show crash of StartMenuExperienceHost.exe caused by ControlLib.dll each time start menu is pressed.

 

I have found that if I disable the Display Adapter in Device Manager (Intel Iris XE) then re-enable it, start menu starts working again until I restart my computer, then it stops working until I disable the display adapter again.

 

I have updated to the latest display adapter driver.

 

So far I have tried an upgrade, run SFC scans and disk check scans, and re-installed windows to no avail. Rolling back to Windows 10 works fine but when upgrading to Windows 11, the issue returns.

 

Any ideas would be greatly appreciated.
