Hi,
Translation:
The closing or rather crashing is reported only for the Android build and while we are unable to pinpoint the exact root cause, it seems that the phone players use has a great impact on the issue itself, some people have also reported this problem, others didn't
Currently there's only some kind of "workaround" for that problem - the most helpful solution is to go to the game app settings and clear the CACHE (not STORAGE, as this would also delete your save data) and reboot your phone
If this doesn't help then the second solution is to keep opening the game until it opens (for real, that's what helped some people)
If all of the above fail, then I'm afraid you'd need to try to reinstall the game
Hope this helps,
Cheers
