Impossible to open Windows 10 apps - Event 5961 0xc0000364

Question

_{Friday, November 22, 2019 9:44 AM}

Hello,

I've recently been informed by users who have a Windows 10 Pro device enrolled in our Intune/O365 that they can't open Windows 10 apps like Calculator, Calendar, etc...

When I check the eventvwr for the Apps, I can see the following kind of error each time they try to open one app:

Event 5961, Apps. Activation for Microsoft.WindowsCalculator_xxxxxxxx!App failed. Error code: Unknown HResult Error code: 0xc0000364. Activation phase: PLM prepare for activation.

I tried the following:

- terminate and repair the app from the app setting: didn't fix it.

• used sfc /scannow: nothing to report
• used dism to repair: didn't fix it.
• I tried to uninstall the app on a machine and wanted to re-install them using different powershell CLIs but Windows Store is included among these apps so I can't run it (and we block it anyway).
• I ensured there was the necessary folders and files in C:\users\username\appdata\etc...> : all seems fine
• Used a local admin account: same.

Do you have any ideas on why this happened and on how to fix that ? It's not related to only one device.

Thank you by advance.

Ok, I think I found the reason.

It was because of a new GPO configured from Intune that prevent store app to run.
While Windows 10 1909 was installed it was reporting the unknown error I mentioned.
After I uninstalled KB4524570 and KB4517389, it was then reporting that the Administrator blocked the app by GPO so I checked the GPO for the devices in Intune and could spot the faulty one.

I don't know if it will help anyone.

Thanks.
