application error while trying to deploy

I have deployed my app onto the environment plenty of times however now I am receiving an error that only states that the application is unable to start and to check the alerts and logs. I figured this was due to the new app pkg so I tried to deploy an older one however I am still receiving the same error message. can somebody please assist?      this is what is displayed under alerts  and a brief snippet of what the log says

The error seems to point to scheduled events. Could you double check those? Did you add a new scheduled event? Try setting those events again to see if that solves your issue.
