Can't open Sonarr -OSX

Just updated to newest maintenence update and can no longer open Sonarr. OS X log reports - Service setup event to handle failure and will not launch until it fires. What does that mean and how do I get running again?

[UPDATE] Had to use backup copy of .config folder to correct problem. Still would like to know why this happened.

Thanks in advance!

Would need to see log files of Sonarr starting up.

The log file was lost when I restored .config folder from a backup… I’ll remember to save the log if this ever happens again.

Thanks.
