Microsoft: Windows 11 24H2 bug crashes Explorer and Start Menu

Microsoft has confirmed a critical Windows 11 24H2 bug that causes the File Explorer, the Start Menu, and other key system components to crash after installing cumulative updates released since July 2025.

This bug affects users who log in after applying the cumulative updates and those using non-persistent operating system installations (such as virtual desktop infrastructure environments), where app packages must reinstall each session. On impacted systems, it causes issues for multiple essential Windows 11 shell components when XAML dependency packages fail to register properly after updates.

As Microsoft explained in a recent support document, applications that depend on XAML packages (specifically MicrosoftWindows.Client.CBS, Microsoft.UI.Xaml.CBS, and MicrosoftWindows.Client.Core) aren’t registering in time after an update is installed, a timing issue that cascades through the system, preventing critical interface components from initializing properly.
