How to solve ‘Start menu error’ after installing Windows security update in July
Security upgrades in Windows 11 often create operating system issues. The same is true for this month’s security patch. Users that updated the most current version of KB5015814 reported issues with the Start menu, which is at the heart of the user experience.

The Start menu seems to hang while launching and exiting apps, according to BetaNews. Given that the Start menu is the primary method for locating and starting apps, this issue may have a substantial impact on the user’s workflow.
The problem with KB5015814 extends beyond the mistake in the start menu. Many customers complained that the update could not be installed. 0x8000ffff, 0x8007007e, and 0x80073701 are the most common error codes. Some users have even reported endless boot loops. A manual reset action is normally necessary in this circumstance.
Assuming there is no long-term harm from not applying the security update, Microsoft may be lucky that it cannot be updated until an official remedy is published.
