I created a dupe of your report and i came here because of it

Wierd. It is like un/installing VirtualBox without restarting and it makes the the internet unusable until you restart. But this goes on even restarting everything does not work.

Here's my Experience playing MCPE:
The game does not save until you exit the world and unfailliar place is where the game last saved before you moved into your place and build the Buildings and idk why your game freezes.

I have a similar glitch on my old WinXP PC:
I Toggled the fullscreen mode on and then toggled it back to windowed mode and suddenly BAM! BSOD!!!!!! I'm not kidding and it happens everytime i do it.

Have you install a mod in the game? If yes, I think you installed the Herobrine mod Because it make mobs around Herobrine attack you.
