Upgraded to build 10122, Project Spartan crashing. Any fixes?

[Protocol Rahul]

Project Spartan is now pinned and is shown as @{Microsoft.Windows.Spartan_...so in}, both in app list and start menu. As soon as I click it crashes, showing + tab that's it.

On dragging an app from app list into main start screen, the start screen becomes unusable and is blacked out. (Restarting the explorer fixes it.)

Cortana and rest of the microphone dependent app not recognizing microphone.
The win32 apps pinned on start screen are blurred(enlarged I guess.), pinning apps through context menu doesn't work I guess, dragging seems to be the only option.
In terms of stability this build seems to run worse than 10074, weird.

I really want to use spartan, so if any one has a fix (registry related), post it here.

Same problem with Spartan (EDGE) here, and yes I also have the impression this build runs not that smooth as 10074
