Mail & Calendar won't open after downgrading from Creators Update
Hi
I recently updated manually my system to the Creators Update. As a result, It made my pc slow so I decided to go back to the previous version through settings. When I did so, everything came back to normal state except for the Mail and Calendar apps which when I click on either of them won't open (I barely see their window frame appears and disappears for 1 second).
I tried lots of methods found on the net but none has solved this problem (PowerShell method, Troubleshooter...). I can't even install any updates fro any app in Windows store (Error).
Thanks in advance for your help.
Windows 10 Home 64bit (14393.1066)
