Windows 10: Problem Uninstalling Camera App

My Surface Book 4 camera has stopped working. Was OK in April when I last used it - now just a blue screen with the text 'Camera' at the top left for a second or two then nothing.
A crash log is written, but it tells me nothing useful. I note that the May Win10 update included several camera-related items - which may or may not be related.
Windows Store tell me that an upgrade is available, but when I try to install the upgrade, I get error code 0x80073CF6.
Following the Microsoft advice for Windows Store problems did not help.
The best approach seems to be to uninstall the Windows Camera app and reinstall from scratch. But uninstalling fails.


The details:


Following the steps at this tutorial:

Run PowerShell as Administrator


PS C:\WINDOWS\system32> Get-appxpackage -allusers *windowscamera* | Remove-AppxPackage


I get this error (with or without -allusers):


Remove-AppxPackage : Deployment failed with HRESULT: 0x80073CF6, Package could not be registered. (Exception from

wekyb3d8bbwe.xml failed with error: The system cannot find the file specified.


And indeed, I have no such file - my version is


Microsoft.WindowsCamera_2016.325.60.0_neutral_split.scale-150_8wekyb3d8bbwe.xml


I have scale-150, where the uninstall is looking for scale-200.


And there is a subdirectory of the same name, without the .XML.
I cannot rename the file and subdirectory to the expected name (and such a brute approach would be risky regardless).
So, how do I remove the Camera App?


I also have the same problem with the 3D Builder, Groove Music and Films&TV apps. All say 'Update available', but none will update - error code 0x80073CF6 on each.

Windows 10 camera app not working

I can't uninstall the camera app from the start screen as it is a default app. I have found out how to do it but I now wonder if the camera app is the problem. It takes photos fine but can't save to the camera roll. So is the camera app the problem or
is it the Photo file app?

 

Help broke my camera on my N8

This seems to be even more of a problem in Belle also.

The camera wors ok at first, but If any camera app is used and associated to camera, the camera will no longer work on its own, but continues to work through the app.

If the apps are uninstalled, you cannot use camera until a complete hard reset is done.

Seems to me it needs a fix to "reconnect" camera if an app isclosed.
