Microsoft pushed a small new update to Windows 10 as a non-security cumulative update for Windows 10, Version 1903 on October 24, 2019 (KB4522355).
The Windows 10 1903 update KB4522355 was sent to correct the Start menu issue that many users were experiencing. However, it is reported that the issue wasn’t resolved with that update and is still present with some users.
Many of you may not be aware of the issue as you may not be facing. The company has created a GIF to show you the issue.
When you bring the cursor on the Start button and click on it, the cursor goes into a loading cursor which means something is loading but that doesn’t happen. After a few seconds, the cursor comes back to normal and the Start menu doesn’t even load.
When taking a look at the details in the task manager, it appears that the StartMenuExperienceHost.exe process tries to launch, but then is immediately ended – at the same time the start menu crashes.
The present solution is using any app from the Windows File Explorer with .exe at the end of every app.
The other method currently working is uninstalled the update that is causing the issue which is KB4517389 and/or KB4522355 and then patches your PC with October 3rd update with KB4524147 and OS Build 18362.388.
