Hi,
Please check if there is any restore point before this issue, if so, please restore system to that point to see if issue persists.
If we cannot get this fixed, please try to scan system file by run following command as Admin:
SFC /scannow
If you get error message Windows Resource Protection found corrupt files but was unable to fix some of them. Please zip and post back the CBS.Log under %WinDir%\Logs\CBS\CBS.log on skydrive and share the link here.
Meanwhile, please help to collect app crash dump file by following the suggestions Andre’s first post in this thread:
