Well, this was the solution. Un-install and re-install XBox and Gaming Services. Why, the last resort was to check the Event Viewer and that pointed to this error.

Faulting application name: WinStore.App.exe, version: 0.0.0.0, time stamp: 0x6ab5a3b1

Faulting module name: gameplatformservices.dll_unloaded, version: 10.0.26100.8569, time stamp: 0x86ae99ec

Exception code: 0xc0000005.... blah blah blah

So I then search Gemini for the failing module name above. Which pointed me to a YTude video which instruction to resolve the problem. Steps: un-install Xbox, reboot, install Xbox, reboot, install Gaming Services, reboot. Open Store app, result: no crash. Clean Event Viewer.And the "pause store updates" issue was solved through these steps:

Fix via Registry Permissions 1. Press the Windows Key + R, type regedit, and press Enter to open the Registry Editor. (Always back up your registry before making changes.) 2. Go to this path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\InstallService 3. Right-click InstallService, choose Permissions, select Users, and check the box to allow Full Control. 4. Go to the subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\InstallService\State 5. Right-click State, choose Permissions, select Users, and check Full Control. 6. Close Registry Editor and reopen the Microsoft Store to pause updates normally

    Hi,

    Since the issue started after installing Windows 11 26H2, the Microsoft Store app or its components may be affected.

    Try the solutions below to see if they can resolve the issue:

    1. If you're using a VPN or Third-party antivirus program, try temporarily uninstalling it to see if the problem goes away.

    2. Try resetting the MS store cache.

    Press Windows + R then type 'wsreset.exe -i' (without the quotes)

    Hit Ok, wait 10 seconds then try to check again.

    3. Try uninstalling and reinstalling the Windows Store.

    Press Windows Key + X and choose Windows PowerShell (Admin). Copy and paste the command below and hit Enter.

    Get-AppxPackage -Name "Microsoft.WindowsStore" | Remove-AppxPackage

    Note: Please complete the process before proceeding.

    After that, reinstall the Windows Store. Press Windows Key + X and choose Windows PowerShell (Admin). Copy and paste the command below, then hit Enter.

    Get-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

    Wait 2 minutes, then reboot your computer and try again.

    4. If that fails, the next step is to try System Recovery without deleting your files and apps.

    Click the Start menu > Settings > System > Recovery.

    Choose Reinstall Now under the section labeled 'Fix problems using Windows Update.'

    Once completed, your system will restart. Please check afterward.
