Alarms are not working

Question

I've been facing the issue of missing alarms for a week. I can set alarms successfully, it displays in notification but not running.



Though if I try to check it will have work or not by setting alarms after 1-2 minutes, then it works ok. But if I set alarm before sleeping then it doesn't ring on morning.



One another thing may be related: I'm getting "Unfortunately clock has stopped" alert randomly about 2-3 times in a day (though it is not happening exactly while setting alarms).



So, I'm not getting what's going wrong with alarms. How can I recognize the issue and fix it?



Note: Running (non-rooted as running under time period of warranty) Android 6.0 on Lenovo .
