Hi! This crash happens because your device has less than 4 GB of RAM, which prevents the game from running properly. When an app uses too much memory, iOS automatically closes it. What could help is to close all the apps on your device, restart it, and then only launch Chants of Sennaar, with no other apps running in the background.
