Need help! Windows 10 start screen/apps not working

So I have window 10 technical preview, I decided to try and refresh whilst saving the data because it was running slowly, now it doesn't work, the start screen won't open, and the apps won't even run. I've updated it seems and nothing seems to work, also I created a backup on my USB stick but the option to rollback to 8.1 doesn't appear in the setting menu anymore. The store doesn't open either, and my region/language are set to US.

Please help!

I am actually having the exact same issue. I installed the new technical preview but when I open up one any of the apps nothing loads or it just kicks me back out.
