Since a few days, several 'modern' apps (including Mail, Skype, News, Calendar) are crashing when launching them.
The event log shows the following errors:
Event 54, AppModel Runtime
Modification was detected in package Microsoft.SkypeApp_126.96.36.19911_x86__kzf8qxf38zg5c (C:\Program Files\WindowsApps\Microsoft.WinJS.2.0_1.0.9600.16395_neutral__8wekyb3d8bbwe\css\ui-light.css).
Event 59, AppModel Runtime
App Integrity terminated an application. Integrity check for microsoft.windowscommunicationsapps_17.4.9600.16384_x64__8wekyb3d8bbwe returned 0.
I am not aware of any changes to my installation (except the regular Defender updates and a few new drivers over the past couple of days.
How can this be fixed?Tuesday, September 24, 2013 5:15 AM
Firstly, If you have not tried system restore, I suggest you have a try to check if we can get rid of this problem.
How to restore, refresh, or reset your PC:
If it doesn't work, I suggest you run Application troubleshooter to check the result.
Run Application troubleshooter:
Download and run the Modern UI App troubleshooter and check.
If the issue persists, we try to modify the setting below to test it.
1.open Control Panel>>Language>>Change date, time, or number formats.
2.In Region dialog box, change the Long time and Short time to anything that doesn't have "tt" in it.

Thank you for your response. I tried everything you mentioned except the PC refresh (I am a bit hesitant here, because it looks like I'd need to reinstall all non-modern apps, Office etc), but with no success. If there are no other ideas how to track this issue down I'll do that though.

I had refreshed my PC, and it worked for a few weeks. Right now, this issue occurred again, after an update to the 'Maps' application was installed through the store. I tried all the steps mentioned by you (except the refresh), but it doesn't work - any idea? I don't really want to do a refresh again (always a few hours to get everything up and running again)

If the issue persists, I suggest you uninstall the Map app and reinstall it.
Hope these could be helpful and keep post.
