How Do I Fix Exception code: 0xc000071f

Every time I click the Windows 11 Start button, I get the spinning wheel of death. The Start button then disappears, and I start the process again. The second time always seems to be stable. This is an annoying little problem I'd like to solve.
Technical Information:
Windows 11 Pro
Version 24H2
Application Log:
Faulting application name: StartMenuExperienceHost.exe, version: 10.0.26100.6725, time stamp: 0xcb8cdc8f

Faulting module name: ntdll.dll, version: 10.0.26100.6725, time stamp: 0xf41da127

Exception code: 0xc000071f

Fault offset: 0x00000000000773f9

Faulting process id: 0x3D98

Faulting application start time: 0x1DC384448C381E3

Faulting application path: C:\WINDOWS\SystemApps\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy\StartMenuExperienceHost.exe

Faulting module path: C:\WINDOWS\SYSTEM32\ntdll.dll

Report Id: 6d7bed71-f213-468f-919a-4a1c61ea313d

Faulting package full name: Microsoft.Windows.StartMenuExperienceHost_10.0.26100.4768_neutral_neutral_cw5n1h2txyewy

Faulting package-relative application ID: FullTrustApp

Running both System File Checker (SFC) and DISM have failed to resolve the issue. Attempts to re register ntdll.dll have also failed to resolve the issue.

Thanks.

    Sorry, I was offline.

    If that process did not resolve the problem, open the Settings App (Windows Key + i).

    Go to System - Recovery.

    Click the 'Reinstall Now' button in the 'Fix problems with Windows Updates' section and wait for that process to complete, this process will not affect your files, settings or installed apps.

    Open Task Manager (Ctrl + Shift + Esc)

    Click File - Run new task

    Tick the box marked 'Create this task with administrative privileges'

    Type powershell into the box and click OK

    Run this command and press Enter:

    Get-AppxPackage Microsoft.Windows.ShellExperienceHost | reset-AppxPackage

    When that completes, run this command and press Enter

    Get-AppxPackage Microsoft.Windows.StartMenuExperienceHost | reset-AppxPackage

    When that command completes, close Powershell and restart (not shut down) your PC to apply the change.
