Windows 10: Cortana, Search, and MS Store aren't functioning properly

Window 10 Observed behaviors:Cortana crashes immediately upon opening.Search crashes immediately upon opening, Both from the taskbar as well as File Explorer.Store opens, will search for apps, but crashes when I try to access one.I've been through every commonly known repair and update including a Windows repair.However, if I log out of Cortana, it won't crash... until I log back in. Knowing this, I created a second user account and everything works in the local account. I went back to my user account disconnected from the Internet and it still doesn't work. Therefore, the issue is with my use

Windows 10 Start Menu, search and Cortana still not functioning correctly

I had some issues with Start Menu not functioning. this was solved in a post by a Microsoft Engineer Giridhar J. However, although the Start menu is now functioning along with the notifications. there are some glitches still.

I cannot pin folders to the start menu. Search and Cortana still does not work properly. Search is glitchy at best having to click on the start button then immediately click in the search box for it to work. Cortana does not work and is not listed as a app
any more.

Any suggestions?
