On a guess I reckon it's a Chinese note issue causing Play store to crash. As you know Play store is not available in China and it probably doesn't like the China hard ware, probably an incompatible bit of code. If the device seems to work OK and you can use Gapps (Google apps) well enough, I wouldn't worry too much it almost certainly starts up again of its own accord once it reports stopping.
All the above is just an educated guess, seeing I'm the only one regularly here that posts I'd thought I'd answer.
