Microsoft has released an emergency fix for freezing and crashing app issues caused by September's KB5005565 and KB5005101 cumulative updates.
With the release of the Windows 10 KB5005101 preview update and the KB5005565 cumulative update, Microsoft states that users may have experienced app freezes, app crashes, and the inability to launch an application.
Microsoft has rolled out a fix using the Known Issue Rollback feature, distributed to Windows 10 devices using Windows Update.
Windows users can also install the fix immediately by running one of the following commands from a Windows 10 elevated command prompt.
If Windows telemetry and diagnostics indicate that a large audience of Windows 10 users are affected by a new issue, Microsoft can release a Known Issue Rollback fix to disable the new code causing the issues, as illustrated below.
While these fixes are distributed via Windows Update, they are not delivered as an actual update.
