if you use a lot of TP, then it will happen like that...
try to reload the game, usually you'll stuck on the same screen again...if that's the case, you will need to rename OBB, uninstall game, re-install original version, rename back obb, and reload game, it will pass that screen. once you passed that screen, reverse back the process of install/uninstallation...
and avoid using too many TP.
if your hung/crash is not because of that...then i have no idea what that is...wait for 2 mins, if situation is not improving, then do the steps above
good luck
