Open Logic Builder programs (You'll see red "0" on the program, indicates program running on nothing when should be)
You can also go inside the program to select "Tasks/Programs" to open the slider to select "Tasks"
There you will see the task summary as faulted and main routine failing
You can also see it if you go to the Show All Targets. Now you can look below on the issue regarding routine error to resolve this.
